Much like author Loren D. Estleman, private detective Amos Walker has long been reluctant to embrace technology; it was not until recently that Walker got his first cell phone. Now, in Infernal Angels, Walker is hired to do a twenty-first–century job—recovering stolen HDTV converter boxes. Before long, the case turns old-school: All the suspects and the man who lost the boxes are murdered, and Walker ends up working with both the local police and the feds of Detroit. 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 and the person behind the trail of dead bodies. Old friends and even older enemies will resurface before this story is done, and Walker will have to take a few beatings if he wants to bring the drug smugglers to justice. This old dog still has a few new tricks, and there hasn’t been a case yet that Walker couldn’t crack.
