Burn Marks (V. I. Warshawski Series #6)

Someone knocking on the door at 3 A.M. is never  good news. For V.I. Warshawski, the bad news  arrives in the form of her wacky, unwelcome aunt Elena.  The fire that has just burned down a sleazy  SRO hotel has brought Elena to  V.I.'s doorstep. Uncovering an arsonist  — and the secrets hidden behind Elena's boozy  smile — will send V.I. into the  seedy world of Chicago's homeless... into the Windy  City's backroom deals and bedroom politics, where  new schemers and old cronies team up to get V.I.  off the case — by hook, by crook, or by  homocide.
