The story begins with a murder in Whitechapel. The action takes place in different eras. Four detectives try to unravel the crime in different periods of time: the successful Edmund Hillinghead from the late nineteenth century, the desperate adventurer Karl Whitman from the 1940s, investigator Shahara Hasan from the 2010s, and Maplewood from the post-apocalyptic 2050s, who suffers from memory lapses. Through their collective efforts, these four heroes, whose lives are not connected, come together to uncover a conspiracy that spans one and a half centuries.
