The Rhodes Case

"Janet Markham is both excited and nervous that Edward Bennett is coming for another visit. The handsome man has made no secret of the fact that he’s interested in being more than friends with Janet, but he’s usually too busy to pursue her.
His job with a secret government agency keeps him travelling around the world, leaving Janet on her own at Doveby House, the bed and breakfast she runs with her sister, Joan.
While Janet is attracted to the man, she’s not sure she trusts him. That trust is further challenged when he tells her that she needs to pretend she’s never met him before when he arrives at Doveby House with his guest.
Just hours after the two men arrive, Janet and Joan see a news bulletin about a wanted man who bears an uncanny resemblance to Edward’s guest. Break-ins at houses in the area worry the sisters."
