Kolchak arranges to meet an informer at the Trevi Salon. But the man falls from an unoccupied top floor studio before Carl can learn what he knew. Now the mob is after Carl, and worse than that, so might be a supernatural force. A bit of research leads Carl to some people who might be able to help him. But all magic benefits from a little misdirection, and Carl has to correct his mistake before the real culprit's plan succeeds.
