Showing Mr. Monk Goes to Germany by Lee Goldberg

Adrian Monk is on a roll solving murders as fast as they come, and not counting his Wheat Chex until they're in the bowl. But when his therapist, Dr. Kroger, leaves for Germany, Monk can't tie his shoes, forgets how to swallow, and loses track of his blinking. Desperate, he follows Dr. Kroger to Germany where he sees a man with six fingers. The man responsible for his wife's death or was it just his imagination? Now Monk has to deal with his phobias and the unfriendly polizei to find his man.
