Touching Evil

Greg has a special talent he'd give anything to be rid of. After an accident many years ago that left him in a coma, Greg woke up to find that he could touch things and know what had happened to them. Too bad he can't control the talent enough to keep it from overwhelming him. He's lived with it long enough that it he can make it day by day, but when he starts being stalked, he has to depend on his friends to help him cope.
The only good thing his gift has brought him is Artie, an overprotective cop with a psychotic cat and a great bedside manner. Artie is all about helping Greg cope, and about finding out who's threatening his friend. Through grisly gifts and terrifying attacks, Artie stays by Greg's side. Even ordering take-out can be an ordeal for Greg, and Artie is happy to run interference. Greg hasn't touched anyone without pain in years, but with Artie he finds he has someone to lean on, even as the stalker finds new ways to torment him.
Can the two of them find a way to solve the mystery of Greg's tormenter before one of them gets hurt?
