and some unlaced canvas shoes, he staggers up the path and falls down in agony nearby. Holmes and Stackhurst rush to help him, but it is too late. The young man dies, uttering the words “the Lion’s Mane” with his last breath.

As the coat falls from the dead man’s bare shoulders, Holmes and Stackhurst see that his back is covered in long, bleeding lines “as though he had been terribly flogged by a thin wire scourge.” Holmes notes that “The instrument with which this punishment had been inflicted was clearly flexible,” as the markings are curved around the young man’s shoulders and ribs.

The dead man is Fitzroy McPherson, the science master at The Gables college. As Holmes and Stackhurst stand over the body, another familiar figure, Ian Murdoch, the mathematics master from the same establishment, arrives. Holmes describes him as a

sinister, aloof, strange character, and tells the reader that Murdoch had once thrown McPherson’s dog through a plate glass window in a fit of temper. Murdoch is clearly a violent man—possibly with a grudge against McPherson. The reader’s interest is piqued.

Holmes investigates

Murdoch is dispatched to summon the police from nearby Fulworth while Holmes begins his investigation. He sees signs that McPherson had fallen over several times as he ascended the cliff path. Down on the shore, Holmes sees some naked footprints that suggest McPherson had gone into the lagoon in which he was planning to swim. However, his towel is folded and dry, so the detective concludes that he could not have gone into the water. There is no one to be seen nearby and no other clues.

Holmes returns to the body to find the police have arrived. They discover a note in McPherson’s pockets indicating an assignation: “I will be there, you may be sure— Maudie.” When the police search McPherson’s rooms, they find letters revealing a secret affair with local Fulworth beauty Maud Bellamy. It seems unlikely the two would arrange to meet in such a public place as the lagoon if they were trying to keep their affair secret. It then emerges that some Gables students would have gone to swim with McPherson had Murdoch not held them back in class. Holmes pointedly asks if it were “mere chance” that McPherson was alone, throwing the reader’s suspicion on

Ian Murdoch

The mathematics master, Ian Murdoch, is set up as the villain of the story. He is described as having “strange outlandish blood”, as well as swarthy features, coal-black eyes, and a ferocious temper. In the Holmes tales, Conan Doyle often used the popular Victorian idea that a criminal type can be revealed in physical appearance (see p.188). Here, however, he is using this stereotype to mislead the reader into thinking Murdoch must be the murderer.

the soft freshness of the downlands in her delicate colouring.” He learns that she and McPherson were engaged, but that they kept it a secret from both of their families to avoid upset. As we learn later, Murdoch has just told her that her fiancé is dead, and she is eager to offer Holmes any help that she can with the investigation, but can offer no real clues. It seems, however, that Murdoch was, and perhaps still is, in love with her. Suspicions are settling on the mathematics master, who, as Holmes notes, has taken the earliest opportunity to get away by provoking Stackhurst into firing him. He demands that Murdoch’s rooms are searched.

Holmes’s epiphany

Holmes goes home to ponder the mystery, and news then comes that McPherson’s faithful Airedale terrier has been found dead at the lagoon where his master died, its little body contorted in agony. Holmes is at a loss what to think. There is something nagging at the back of his mind, however. He goes for a walk to the lagoon to clear his head, and on his return suddenly remembers what it was: “Like a

As a rival for Maud’s attention, Murdoch is a natural suspect. However, Maud states clearly that he stepped aside as soon as he found out that she had chosen McPherson. And Stackhurst insists that Murdoch and McPherson had put the incident of the dog behind them and were now firm friends. Yet Holmes ignores these witness statements and continues to suspect Murdoch. It is strange that Holmes, who is generally so logical and rational, should be led astray by prejudice at this late stage in his career.

flash, I remembered the thing I had so eagerly and vainly grasped.” He reminds the reader how his brain is like a “crowded box-room” packed full of data, or “out-of-the-way knowledge,” that might one day come in useful. This idea of the “box-room” (or “brain attic” as Holmes also describes it) dates back to the very first Holmes book (A Study in Scarlet, pp.36–45), and is a key image Conan Doyle uses to describe Holmes’s way of thinking, which various psychologists have embraced. Russian-American psychologist Maria Konnikova, for instance, has adopted the “brain attic” metaphor as a useful way of understanding how humans store information, organize knowledge, and use it to devise strategies for clearer thinking and “mindfulness.”

In this particular case, however, the reference to the “brain attic” merely serves to remind Holmes ❯❯

282 THE FINAL DEDUCTIONS

to look in his real attic, in which he finds a little “chocolate and silver” book, entitled Out of Doors. Written in 1874, this was in fact a genuine publication by a popular Victorian natural history writer at the time, John George Wood (1827–1889).

Delayed revelation

Having verified his suspicions by consulting his book, Holmes has, to all intents and purposes, solved the mystery of McPherson’s death. But Conan Doyle sustains the story a little longer, tantalizing the reader by introducing a sequence of obstacles that prevent Holmes from revealing his great solution.

First comes Inspector Bardle, who Holmes describes as “a steady, solid, bovine man,” to suggest that he is trustworthy but not especially intelligent. He asks for Holmes’s opinion as to whether he should arrest Murdoch before the suspect leaves town. The fact that Murdoch is hot-tempered, has argued with McPherson in the past, is in love with Maud, and is preparing to leave Fulworth—combined with a lack of any other likely suspect—all indicate guilt to the inspector. But Holmes points out that Murdoch

The sting in the tale

Holmes’s source for this story (Out of Doors) was correct. A giant jellyfish called the lion’s mane— the world’s largest—really does exist. The biggest specimens have a bell up to 10 ft (3 m) wide, with tentacles that can extend 100 ft (30 m) or more. The lion’s mane is found primarily in the North Atlantic, and grows especially big in cold Arctic waters. Small specimens are often seen on the south coast of England, but giant ones may appear occasionally, as explained in the story by the fact

has an alibi, and that the evidence against him is flimsy. The great detective also tells him that he has examined a photograph of McPherson’s wounds, and teases the inspector—and the reader— with possible explanations for their strange nature. Then, just as he is about to explain the truth of the matter to him, Murdoch bursts in and delays the revelation further.

Murdoch is in a bad way. He is in terrible agony, branded with the same weals on his shoulder as

that the severe southwest gale could have carried it beyond its normal range.

The lion’s mane’s tentacles have thousands of stinging cells. These contain poisonous threads that unfold and launch themselves like harpoons into a victim’s body. They leave large red welts or ridged zigzag lines in the skin, along the path of the jellyfish’s lashing tentacles, just as Holmes describes. These stings can cause intense pain or, in very rare cases, death.

McPherson. After knocking back several large doses of brandy, he finally falls into an unconscious stupor. Stackhurst, who had met Murdoch on the cliff and followed him in to Holmes’s house, pleads with Holmes to save them from this apparent curse.

Finally, Holmes relents. “We will see if we cannot deliver this murderer into your hands,” he announces, leading the inspector and Stackhurst down to the lagoon on the shore. As Holmes scans the pool below, he yells triumphantly, “Cyanea! Behold the Lion’s Mane!” and in the water all three men spot the tentacles and globular body of a giant jellyfish. Holmes spies a large boulder above the pool and, at his call to “end the murderer forever,” between the three of them they roll the boulder into the pool to kill the jellyfish.

A natural killer

It seems there was no murder at all and that McPherson, his dog, and Murdoch were all victims of a natural hazard—the sting of the jellyfish Cyanea capillata, commonly known as the lion’s mane. As Holmes shows his

friends in his book Out of Doors when they get home, McPherson is not the first to encounter this dangerous giant jellyfish: author John George Woods explains how he had once had a close encounter with a lion’s mane and was lucky to escape with his life. His book warns swimmers who see a tawny-colored membranous mass that resembles a lion’s mane, “Let him beware, for this is the fearful stinger, Cyanea capillata.”

The stings of these jellyfish are extremely painful, but rarely fatal. However, Conan Doyle is careful to stress that McPherson had a weak heart, and so it is entirely plausible that the stings could kill him, while Murdoch survives the attack.

Holmes on the wane?

In this story, Conan Doyle has employed a fascinating, real-life killer, and Inspector Bardle is full of admiration for the way Holmes has gotten to the bottom of the case. “I had read of you, but I never believed it. It’s wonderful!” the inspector cries. But as Holmes modestly admits, “I was slow at the outset—culpably slow,” and certainly this is a tale that has not shown him at his most perceptive.

Holmes assumed from the start that McPherson’s death was murder and that there was a human killer, possessing a flaying instrument, to track down. At first he suspected Murdoch of being the murderer, but this was based largely on the man’s appearance and character rather than fact—the type of red herring that Watson might have fallen for.

Holmes was misled, he says, by McPherson’s dry towel: it made him think that the dead man had never been in the lagoon, and claims that had he found him in the water the true cause would have been clear. However, the observant reader will note that Holmes must have failed to spot that when McPherson died his hair was surely still wet, and that his clothes would certainly have been damp had he thrown them on without drying himself first. Also, when Holmes inspected the crime scene he somehow missed the huge jellyfish. But in spite of these slips, it is ultimately only Holmes who solves the puzzle.

Without Watson as Holmes’s foil, Conan Doyle may have forfeited a little of the detective’s brilliance to the plot. But any fears the reader may have that Holmes’s powers are waning with age and retirement can be allayed: his dramatic undercover work in “His Last Bow” (pp.246–47), set seven years after “The Lion’s Mane,” shows Holmes at the height of his powers. ■

fter a recent first encounter with a new client, referred to him by Scotland Yard, Holmes is in a melancholy mood. The client, Josiah Amberley, is the “retired colourman” of the story’s title, a former manufacturer of art materials and now a pathetic, broken creature, aged beyond his years, his face lined, his posture stooped, and his appearance unkempt.

Amberley claims that his young wife has been having an affair with his chess partner, Dr. Ray Ernest,

and now the pair have gone missing with his life savings. Watson is enlisted as Holmes’s proxy and sent to Amberley’s Lewisham home to investigate. This is an unusual, though not unique, procedure for Holmes, who tends to distrust and double-check Watson’s investigative work, as in The Hound of the Baskervilles (pp.152–61). The report Watson writes shows him at his most creative, giving Holmes ample opportunity to call out his tendency to embroider and embellish the facts.

THE ADVENTURE OF THE RETIRED COLOURMAN 285

Holmes takes charge

Crucially, Watson observes that Amberley is painting a door and passageway in his house with a strong-smelling green paint. Watson also notices a tall, dark, mustached man who follows him when he leaves Amberley’s house. This is enough to engage Holmes’s suspicions. Holmes despatches Watson and Amberley on a wild-goose chase to Essex using a false telegram purporting to come from a vicar named Elman. With them out of the way, he establishes that Amberley’s alibi for the night of his wife’s disappearance (a theater trip) is false. Holmes then breaks into Amberley’s house and discovers, behind the freshly painted door, a sealed chamber with a telltale gas inlet pipe—a perfect murder room. Amberley lured his wife and her suspected lover into the chamber and trapped them there, flooding the room with poisonous gas.
