The subject of identical twins has been on my mind ever since I read a magnificently creepy thriller called Ice Twins by SK Treymayne — a pseudonym meant to sound like a woman, but it fact belonging to the novelist Sean Thomas. Lydia and Kirstie are monozygotic twin seven-year-olds i. Lydia is killed when she falls off a balcony.
