The Mark of Cain

Millionaire Rowland Trowbridge has been found murdered, and his niece is determined to find the culprit. A young boy called Fibsy who worked in Trowbridge's office is able to piece together key clues, showing up the inefficiency of the police investigation so far, and requests the help of skilled detective Fleming Stone. With a whole host of suspicious characters and devious motives, this will be a tricky crime to solve. A classic whodunnit from the skilful mystery writer Carolyn Wells.
