At Corey's urging, a reluctant Dr. Hyatt is staying at a lodge for some much needed rest and recreation. The lodge's handyman is plotting the death of the owner, with the help of an escaped convict. The owner's wife, who is also the handyman's ex-lover, is in on the plot, but is ambivalent. When Hyatt's suspicions are aroused, he calls the Checkmate headquarters, and Jed arrives at the lodge, posing as a guest.
