Summary & analysis
Holmes, wrecked from a marathon case, is dragged to Surrey to rest — where a burglary at Acton's yields nothing but string and a coachman is shot at the neighbouring Cunninghams', a torn corner of paper in his hand promising a midnight meeting.
Holmes works while performing exhaustion: he knocks over a table to disorder a room, fakes a fit to interrupt a dangerous admission, and secretly compares the note's alternating pen pressure — two hands wrote it, alternating words, and blood relation shows in the shared letter-forms.
Father and son Cunningham wrote the lure together and shot the coachman who was blackmailing them over the first burglary — staged to muddy a lawsuit with Acton. The seizure that snatches Holmes from the son's revolver is the performance that closes the case.
Deeper reading
Detection while feigning collapse
The Reigate Squires is a small gem of misdirection aimed at the villains rather than the reader: Holmes, supposedly convalescing, fakes a fainting fit and knocks over a table to seize evidence and derail a dangerous admission. Doyle lets the detective act the invalid to disarm suspects who think him harmless — a reminder that Holmes is as much actor as analyst.
Handwriting as fingerprint
The core deduction is a fine piece of questioned-document reasoning: a torn note written in two alternating hands, betraying a father and son by the hereditary likeness of their script. It is an early, confident use of graphology-as-evidence, and the tight construction makes this one of the more satisfying minor Memoirs.
