The death of a top tennis player, Annie Sharp, in the middle of a major match brings in Bernard Newman, along with his FBI friend Nicholas Prince, one of the many spectators in the stands at the time, to help investigate. While the deceased was engaged to be married to her manager, it is learned she had a secret lover as well and this person seemed to go by quite a few different names. As he searches for the truth, Newman will find other victims.
Superintendent Marshall of the C.I.D. will, naturally, be called in to help out in a large way.
