Description:Law-enforcement officials think they've seen everything until they bump into Elmo Wimples, the inventor of a substance that can make anything invisible. Wimpler's found his niche in life by dropping out of sight--literally--and killing with a device that crushes skulls.
His victims are multiplying, there are no clues in sight, and authorities are groping in the dark. Under suspicion themselves, Remo and Chiun set out to play blindman's buff with the killer no one can see, but they, too, draw a black.
