Edgar Award Finalist: Grand Master of crime fiction Dorothy Salisbury Davis delivers a thrilling tale of Cold War–era espionage and murder.

One afternoon in Manhattan’s Washington Square Park, Eric Mather is approached by two men, Tom and Jerry, with a business proposal: a bit of light espionage that may be considered treason. Eric’s friend and colleague, physics professor Peter Bradley, is on his way back from an international conference in Athens. In his briefcase is a roll of film that must be confiscated to keep the Cold War from turning hot. Bradley won’t miss this little roll of film, they say, and nobody will get hurt.

When Bradley is stabbed to death in an apartment on East Tenth Street, Eric realizes he has made a bargain with the wrong people. Desperate to make up for betraying his friend, he ventures into a shadowy world of danger and intrigue as he sets out to learn everything he can about Tom and Jerry—two foreign agents engaged in an atomic game of cat and mouse.
