Scotland Yard's unlikeliest detective pair-- plucky Irish redhead Kathleen Doyle and British lord turned cop Michael Acton-- are on the trail of a serial killer in the third of Anne Cleeland's mystery series. Kathleen Doyle is on the trail of a killer who seems to be intent on handing out vigilante justice-- killing those who, for one reason or another, have not paid the price for their crimes. But as she gets closer to the killer, other dangers lurk. Solonik has reared his head again, pulling Doyle into his web in unexpected ways. And Acton is acting surprisingly distant, given his usual fascination with his new wife.
