Strangers who linger

There was blood on his hands . . . Everyone believed Greg Marten was guilty. A kindly old priest had been brutally murdered, and Diana Clark had found Greg standing over the body. Greg was a stranger in town, with no proof of his innocence and no one to take his part. Only the fact that the police couldn't find the murder weapon won him even temporary freedom. Diana was an unexpected ally, as eager as Greg to bring Father Denning's murderer to justice, and as unwilling as he to trust this case solely to the police. But as they drew closer to the chilling truth, they realized that someone lingering at the scene of the crime had seen them. And now, that watcher was stalking them, choosing his own time to act.
