Det. Laura Baker is sent to reclusive inventor Simon Ford's island mansion after the millionaire is attacked in his lab and suffers memory loss as a result. Laura is withdrawn from the case when her estranged father becomes a suspect and then disappears. But Simon is certain only Laura can help him, so he arranges for her to pose as his fiancée while they investigate what happened to her father. Stolen Memory (3) by Virginia Kantra is an interesting read. Simon, who discovers he doesn't really like the man he was and tries to change, has a compelling character arc.
