Gilbert Adair

At a Christmas house party on Dartmoor in 1935, Raymond Gentry's dead body is discovered in a locked room. Obviously not a suicide, so how was the murder committed? One of the guests, crime writer Evadne Mount, is on hand to investigate.

During the annual Sherlock Holmes festival in Meiringen, Switzerland, novelist Gustav Slavorigin is murdered. None of the festival guests are above suspicion. Even amateur sleuth Evadne Mount is unprepared for the twists and turns of the investigation which climaxes at Meiringen’s principal tourist attraction, the Reichenbach Falls.

The year is 1946. An actress is murdered on a crowded film set where only six people had the opportunity to commit the crime. What's more all six have a motive.
