When Detective Sime MacKenzie is sent from Montreal to investigate a murder on the remote Entry Island, 850 miles from the Canadian mainland, he leaves behind him a life of sleeplessness and regret.
But what had initially seemed an open and shut case takes on a disturbing dimension when he meets the prime suspect, the victim’s wife, and is convinced that he knows her - even though they have never met.
And when Sime’s insomnia becomes punctuated by dreams of a distant Scottish past in another century, this murder in the Gulf of St Lawrence leads him down a path he could never have foreseen, forcing him to face a conflict between his professional duty and his personal destiny.
