Four and Twenty Blackbirds

A magical maniac is loose in Alanda. The victims are always women, always lower-class, and the weapon is always a three-sided stiletto, most often found among Church regalia. But the killers are never churchmen, and they always commit suicide immediately after the bloody deed. Constable Tal Rufen really cares about his job, and when one of these murder/suicides happens on his beat he becomes obsessed with the case.
