Sure enough, on one foggy afternoon of itchy thumbs, the hapless Ben is implicated in criminal activity by the police - the kind of mistake it isn't easy to explain. Doing a runner, Ben hides in the basement of a deserted house, where he discovers the body of a well-dressed man, shot through the head . . . and much more trouble than he bargained for.The subsequent hair-raising events are charged with all the mounting excitement that made J.
