About the Book

A private investigator is hired to look into a mysterious, high-profile death aboard the starship Halcyon in this fresh new science fiction masterpiece from the "mastersinger of space opera" (The Times) and the creator of the beloved Revelation Space universe. Strap in for a gripping murder mystery.

Yuri Gagarin is a private investigator who picks up small cases from his local community, runs into trouble with the local police, and generally ekes out a living as best he can. He's aboard the Halcyon - a starship, hurtling through space, carrying thousands of passengers with thousands more sleeping the journey away.

Only his usual investigative work - catching cheating spouses, and small time con artists - is about to take a turn. He's hired by a mysterious woman called Ruby Red to look into a death in one of Halcyon's most elite families . . . and then warned off the case again by a second mysterious woman called Ruby Blue. Caught between the two, he's about to be embroiled in a murder mystery in which - at any moment - he could be the latest victim.
