When an old woman experiences dreams of the future, including the murder of a prominent Swiss businessman and a prediction of a car crash, Jonathan must find out what is happening before her dreams of being attacked by a one-eyed man with a sword come to pass.

Maddy is contacted by a man who makes a living investigating the existence of aliens and who claims to have found a real alien skeleton. The US Air Force intervenes and takes the skeleton, but it vanishes on the way to the military base, leaving Jonathan to try to find out where it went without leading the military to Maddy.

A man who claims to have sold his soul to the Devil has a remarkable run of good luck — ranging from finding ancient treasure in his backyard to surviving a point-blank range shooting — but Jonathan and Maddy believe his success may be coming from a more Earthly source than Hell. Adam, meanwhile, has to deal with a rather awkward court case where a woman claims he asked her to perform unnatural acts with a kipper.

A judge on a police protection programme is killed by a rapier blade to the heart after a brief struggle, but only his wife, who insists she's innocent, was in the room at the time, and the only evidence at the crime scene is a torn fingernail. As Jonathan investigates the murder, Maddy and a new friend are investigating the derelict Mother Redcap Inn, where seven men apparently died of fright after looking out of a window in the same room. A connection between the cases is drawn when Maddy discovers the body of a vagrant woman... missing a fingernail.
