By the Pricking of Her Thumb

One of the four richest people in the world may be dead. But which one? A Kubrickian thriller from one of the world's leading authors of SF.

---

Private Investigator Alma is caught up in another impossible murder. One of the world's four richest people may be dead - but nobody is sure which one. Hired to discover the truth behind the increasingly bizarre behaviour of the ultra-rich, Alma must juggle treating her terminally ill lover with a case which may not have a victim.
Inspired by the films of Kubrick, this stand-alone novel returns to the near-future of THE REAL-TOWN MURDERS, and puts Alma on a path to a world she can barely understand. Witty, moving and with a mystery deep at its heart, this novel again shows Adam Roberts' mastery of the form.
