This is the second book in Michael Connelly’s series of novels about semi-disgraced Los Angeles Police Department Detective Harry Bosch. It wasn’t bad. Bosch becomes involved in the apparent suicide of a fellow officer. He isn’t supposed to work on the case but one thing (or one murder) leads to another. Besides, somebody has to figure everything out. The ice referred to in the title is a heavy-duty drug that’s being imported from Mexico. Being the kind of cop he is, Bosch ignores his bosses and takes his investigation south of the border. He even ends up in a tunnel again, as you would expect in another story about an ex-Viet Nam tunnel rat.
