The Professor's Affair (Third Wheel Series 1, Book 3)

Harry sits and stares at the photo. The greasy rag moves up and down the barrel of the rifle in his hands. Sam - the boyfriend - has done it again. The nudity; that angle; the rude nature of the photo. What sort of sadist sends a photo like that to a man? Harry is about to find out as he is drawn into an affair that will leave him and his man changed for life.

This is the third book in this series. You can find all four in the Third Wheel Collection 1.
