The Riddle of the Wooden Leg.

Sauntry, secretary to John Graydon, the wealthy banker, commits many robberies in the city among the wealthy class, gaining a rather sinister reputation. He hides his tracks by placing a wooden leg on one of the good ones, thus leaving a print and a round mark. Graydon's diamond disappears and the chain to which it was tied is found by Limpy Fisher, a boy from the East Side, with a wooden leg.
