Pulse (Dick Francis)

Chris Rankin is a doctor, a specialist in Emergency Medicine at Cheltenham Hospital, but a doctor who also has health problems.

A smartly dressed man has been found unconscious at the local racecourse and is rushed to the hospital, where he subsequently dies. But who is he? Where does he come from? He had no form of identification on him, and no one claims the body.

Doctor Rankin is intrigued by the nameless dead man, obsessed even, and starts asking questions. However, someone doesn’t want the questions answered and will go to any lengths to prevent it, including attempting murder. But no one else believes that someone tried to kill Chris, leaving the doctor no option but to discover who the nameless man is and why he died, preferably before following him into an early grave.
