Previously published in the print anthology Three Blind Mice and Other Stories. The patrons and residents of the newly opened guesthouse Monkswell Manor find themselves trapped by a snowstorm and threatened by a psychotic killer. With a finite cast of characters in this "locked room" mystery, it is not long before suspicions are voiced, and, under growing pressure, even newlyweds Molly and Giles each start to suspect the other of being a killer.
