SUMMARY

Watson is married to Mary Morstan and in practice.

Hall Pycroft has obtained a position with a large securities firm. He was hired by mail so that his employers knew his handwriting but not his face. In the interval between his acceptance and his going to work for the first time, Arthur Pinner contacts him, posing as an agent for a large European company and offering him another position which pays a fantastic salary. Pycroft accepts this second position.

Pinner was in partnership with Beddington who impersonated Pycroft at his job, made casts of the locks and had duplicate keys made. He robbed the firm of a large amount of securities, killing a watchman in the process, but as he was leaving was confronted and arrested by Tuson and Pollock.On his way to meet Pycroft, Pinner buys a newspaper in which he reads of Beddington’s capture and therefore tries to take his own life.
