Dark Assassin

On a patrol boat near Waterloo Bridge, police superintendent William Monk notices a young couple engaged in an intense discussion. Seconds later, the two plunge to their deaths in the icy waters of the Thames. Was it an accident, a suicide, or a murder? Ever the investigator, Monk learns that the woman, Mary Havilland, had planned to marry the fair-haired man who shared her fate. He also discovers that Mary's father had recently died in a supposed suicide. But Mary's friends share their own darks suspicions with Monk, who now faces the mysteries surrounding three deaths. Aided by his intrepid wife, Hester, Monk searches for answers. From luxurious drawing rooms where powerful men hatch their unscrupulous plots, to the sewers beneath the city where poor folk fight crippling poverty, Monk must connect the clues before death strikes again.
