Infernal Angels — Loren D. Estleman

Break out the champagne -- it's the twenty-first Amos Walker noir detective novel!

Much like author Loren D. Estleman, Detroit private investigator Amos Walker has long been reluctant to embrace technology -- he only recently got his first cell phone. Walker is hired to do a twenty-first-century job -- recovering HDTV converter boxes stolen from a retailer whose shop also does vintage resale business. Before long, the case turns old school: both a suspect and the man who lost the boxes are murdered, and Walker ends up working with both the local police and the feds. The converter boxes were being used to smuggle high-grade heroin that's been killing off junkies left and right, and it's up to Walker to track down the missing dope.

Old friends and even older enemies resurface before this story is done, and Walker has to take a few beatings if he wants to find out who has been trafficking the drugs and bring the crooks to justice. This old dog still has a few new tricks, and there hasn't been a case yet that Walker couldn't crack.
