La casa buia

Kenzie and Gennaro are hired by the aunt of a missing 4 year old girl, who's been missing so long that good news is almost impossible. Following a trail started by her worthless mother leads the pair and the police to drug dealers (small time and large), child molesters and other monsters and a tangled web so intricate that it makes what the protagonists have been through before seem like a picnic.

This book was my first exposure to Lehane, and turned me into a devotee for life (probably). Even though I've read this 4-5 times, it had me on the edge of my seat, and got me choked up and horrified by the evil depicted.
