Summary & analysis
Jabez Wilson, a red-headed pawnbroker, recounts the most absurd employment in fiction: paid four pounds a week by a league of red-headed men to copy the encyclopaedia — until a card on a door announces the league is dissolved.
Holmes asks about the assistant who found the advertisement and works for half wages; a walk to Saxe-Coburg Square lets him thump the pavement, note the assistant's dirtied trouser-knees, and map what lies behind the shop: the City and Suburban Bank.
The absurdity inverts into geometry — the league existed to move one man out of one building for four hours a day while a tunnel advanced. The vigil in the bank vault catches John Clay rising through the floor, and the story closes on the famous consolation: l'ennui, escaped for one evening.
Deeper reading
Comedy as camouflage
The genius of The Red-Headed League is that its absurdity is the disguise. A scheme so ridiculous — paying a man to copy the encyclopaedia because of his hair — seems too silly to be sinister, which is exactly why it works as a cover for the tunnel being dug beneath the pawnshop. Doyle understood that the reader, like the victim, dismisses the ludicrous, and hides the real crime behind a joke. Holmes\'s lesson is to treat the outré as a clue, not a distraction.
A favourite of its author
Conan Doyle ranked this among his best Holmes stories, and it is easy to see why: the misdirection is fair, the reasoning (worn trouser-knees, a thumped pavement) is clean, and the closing note — Holmes\'s weary remark that such little problems are his escape from the ennui of existence — is one of the canon\'s most quietly revealing lines about why he does the work at all.

In this story: The reasoning pivot: any scheme this elaborate about a man so unremarkable must be about his premises, not his person — the absurd premise is the misdirection to analyse, not dismiss.
