After a student choir’s practice session at a Helsinki villa turns deadly, Detective Maria Kallio finds herself in the center of the action – and her first murder case. Somebody in the group wanted playboy Tommi Peltonen lifeless, but that’s one song these suspects won’t sing. Behind the choir’s jovial facade is situated bitter passion, as well as the victim’s seemingly perfect existence hid a bunch of sins that produced him a target of almost everyone in the villa.

As a young feminine – and a redhead to boot – Maria knows that resolving this case will help her overcome her perceived shortcoming in the eyes of her colleagues. But as the situation takes startling twists and changes, and close friends and foes become interchangeable, will she be able to piece together the clues prior to the killer strikes again?
