Who Killed Bob Teal? - a Continental Op Short Story

A classic mystery from Dashiell Hammett. 'Back Mask' mystery and detective crime magazine carried the story in November 1924. They introduced it this way: "Operative Teal went out to shadow a thief, who didn't even know he was suspected. Seven hours after Teal left his agency's office, he was found dead - shot to death. Whose hand cut him down?" Amusingly, 'Black Mask' credited the author on the title page as, "Dashiell Hammett of the Continental Detective Agency," which of course is fictitious!
