Only two kilometers wide and three long, Entry Island is home to a population of just more than 100 inhabitants, the wealthiest of whom has just been discovered murdered in his home.
Covered in her husband’s blood, the dead man’s melancholy wife spins a tale for the police about a masked intruder armed with a knife. The investigation appears to be little more than a formality–the evidence points to a crime of passion by the wife.
But homicide detective Sime Mackenzie is electrified by the widow during his interview, convinced that he has met her before, even though this is clearly impossible.
Haunted by this strange certainty, Sime’s insomnia is punctuated by vivid, hallucinatory dreams of a distant past on a Scottish island 3,000 miles away, dreams in which he and the widow play leading roles.
Sime’s conviction soon becomes an obsession. And despite mounting evidence of the woman’s guilt, he finds himself convinced of her innocence, leading to a conflict between the professional duty he must fulfill and the personal destiny he is increasingly sure awaits him.
