Ex-MI5 Harry Tate is back.

“Harry. Plse make Grosvenor Square tomorrow 18.30. Urgent. Remember Mirovica.”

An atrocity that allegedly took place under Harry’s watch in Kosovo in 1999 returns to haunt him when he receives a summons from an old UN contact. A lone assassin is tracking down all those who were present that fateful night, despatching his victims with cold, skilful efficiency. Who is he and why does he want revenge?

If he is to uncover the identity of this ruthless killer and stay alive in the process, Harry must uncover what really happened in Mirovica back in 1999.
