NYPD lieutenant Norah Mulcahaney, "the best and most believabl woman cop in mystery fiction," investigates a rash of devastating cop deaths. 41 year old Norah Mulcahaney's star is on the rise. Not only has she passed the rigorous NYPD captains exam, thus achieving a long held career goal, but she's also suceeded in adopting a baby boy, whose presence fills her with a joy she never imagined. But her happiness is shattered when, within a month's time, 4 fellow officers die, apparent suicids. Though individual circumstances vary, all the men are found of wounds inflicted by their service revolvers. When Chief James Felix, Norah's longtime frien and mentor, asks her to pay a visit to one of the grieving widows, she is immersed in a controversial case that hits much too close to home. To complicate matters, Norah faces every mother's worst nightmare when her nanny suddenly leaves, forcing her into a childcare crisis. When her superior refuses to approve her makeshift home office, Norah enlists the help of Chief Felix-until her beloved friend nearly becomes the 5th policeman to die. Spurred by the personal turn the case has taken, Norah must prove the deaths were murders, not suicides. She must find a motive and a common denominator, before yet another of New York,s finest is laid to rest. But with nothing to link the deaths beyond the policemen's vague complaints of the flu before they died, Norah's not sure where to look-and she's not feeling too well herself.
