Tim's new assignment has taken him to Amsterdam to follow Barbara Day. One of Ross's agents, Leo Salinger, was killed in a street accident in Amsterdam and Barbara Day was the driver of the car involved. Tim returns to London convinced that the accident was a genuine one. However, Ross still has doubts. When Tim arrives at Barbara Day's flat in answer to her telephone call, she is not there. Instead, Tim finds the body of Martin Cordwell, an American tourist-and a metronome.
