The Memoirs of Sherlock Holmes - The Reigate Puzzle
April of '87, a strenuous case concerning Baron Maupertuis left Holmes ill. More than once, he had spent 4-5 days awake at a time working on the case that the police of three countries had failed.
Watson took Holmes to Reigate in the country to visit Colonel Hayter and to let Holmes have a little fresh air.
They happened to visit the day after there was a break in at one of the other residents. And the night they arrived, there was a shooting. Involved were the feuding families of Acton and Cunningham.
Result: Cunninghams robbed Actons looking for a deed to the land. Their coachman, William Kirwan, was shot because he followed his employers (a father and son team) and witnessed them robbing the Acton's library. They both made up a story to cover their tracks about the shooting.
