One magic place in time, Paris, brings Josephine Ferrell and William Hayes together for an unforgettable summer. But it isn't meant to last.

Eighteen years later, Dr. William Hays is on staff at Keystone Mental Institute and encounters Michelle Andrews, a psychiatric patient at the institute. Deep in his heart, William is sure that Michelle is Josephine Ferrell. He's unable to convince hospital staff at Keystone that a case of mistaken identity has occurred. William decides to kidnap Michelle and take her to a secluded place in the mountains. While he's nursing Michelle back to health, she dreams of a man in her past who had deep blue eyes and was the love of her life.

Williams returns to work at Keystone Institute and learns that Michelle has an identical twin sister, Josephine. He then starts to doubt if his instincts are correct and hopes that he hasn't taken a schizophrenic patient from the hospital. In the meantime, a killer is walking the halls of Keystone Institute.

Detective Ming Delaney and her partner, Tyrese, have been called in to investigate the disappearance of Michelle and the murder of Dr. Meredith Bancroft. The murder occurred around the same time that Michelle disappeared. Det. Delaney and her partner have their hands full as they try to find out what happened to Michelle. The staff at Keystone Institute is being murdered one by one. While William and Michelle rekindle their love for each other, a deadly game of cat and mouse ensues between the two sisters.

The questions are: which sister is which, who will win and is William really with the love of his life or not? DEADLY DOUBLE is a well-told story of good twin versus bad twin. One of them wants it all, no matter the cost. I found this to be an easy, enjoyable read.
