NO DARK PLACE
by Joan Wolf
No Dark Place ($22.00; Jun. 3; 294 pp.; 0-06-019238-0): Most medieval mysteries dip into the past, but it’s quite a fast-forward from Wolf’s sojourn in prehistoric romance (The Reindeer Hunters, 1994, etc.) to the comparatively recent 12th century, when Hugh Corbaille learns that the father he just lost may not be his father after all; Hugh may be the kidnapped heir, and the only witness to the long-ago murder, of the Earl of Wiltshire.
