Henning Mankell - One Step Behind (MP3 EN)

From Random House:
On Midsummer's Eve, three role-playing teens dressed in eighteenth-century garb are shot in a secluded Swedish meadow. When one of Inspector Kurt Wallander's most trusted colleagues--someone whose help he hoped to rely on to solve the crime--also turns up dead, Wallander knows the murders are related. But with his only clue a picture of a woman no one in Sweden seems to know, he can't begin to imagine how. Reeling from his own father's death and facing his own deteriorating health, Wallander tracks the lethal progress of the killer. Locked in a desperate effort to catch him before he strikes again, Wallander always seems to be just one step behind.
