From back cover:

When he rented Riverhead Island to Major Collins, Greg Allison had no idea of the violent chain of events this act would start. He didn't know then that it would cost him Hilda's love - and that she would die. From the first night of the Major's tenancy, when artist Robert Bennett mysteriously disappeared, fear walked unchecked on the island.

Collins' valet, Kurt Forster, arrived with a mysterious message and events happened with frightening speed. Greg Allison was unaware of the plot until he found his wife in Collins' arms - and by then it was too late for him to do anything but wait.

Lovely Amelia Wilder learned too much of what was going on on Riverhead Island, as did Morrie Peters - who met violent and sudden death.

When Allison discovered the secret behind Major Collins, something he thought had died with the war came back ... to kill!
