The Sign of Four

by Arthur Conan Doyle

First published 2019

Mary Marston has received a peculiar gift each year for six years: a single large pearl. Now a cryptic letter arrives, calling her a wronged woman who deserves justice. The anonymous writer demands she come to a meeting, bringing two companions with her. Holmes and Watson accompany the young woman through London's thick yellow fog to this ominous rendezvous. Mary seeks answers about her mysterious benefactor and the meaning behind these expensive gifts. But the detective and doctor remain unaware that dangerous figures move through the same murky streets. A one-legged criminal prowls the fog with vengeance driving his every step. His partner values human life no more than dust. As Mary pursues the truth about her strange inheritance, these violent men close in with their own deadly agenda. The collision between Mary's quest for answers and their thirst for revenge will determine who survives London's treacherous night.
