The story is told from several points of view. From the point of view of the boarders at Maude's boarding house. From the point of view of the killer, told in first person. And from the point of view of the policemen investigating the crime. Thus this story is part psychological suspense and part police procedural. The reader knows from early in the book that the killer lives in Maude Daneson's boarding house (but not the identity, of course).
Most of the narrative is focused on Christmas preparations and plans at the boarding house and the killer's thoughts and and activities. The killings are haphazard, not usually planned in advance, so the series of deaths seem to be the perfect crime with no links to the killer.
Iris Loring, a freelance artist, serves as the character who introduces the tenants of the house. As a distant relative of Maude, she has her room for free in exchange for serving as the housekeeper. As the tenants enter and return to the building each day Iris meets then as she does her chores and decorates the hallway for Christmas.
Again the style of each chapter feeding hints about the villain but leaving the reader dangling annoyed me (as in The Hunting Party by Lucy Foley), but overall the story is a page turner and a fun Christmas read (and short). The setting of the boarding house is an appealing one. A group of disparate persons, some young, some older and retired, provide some interesting characters and relationships. The policemen on the case do not play a large part, but the characterization of the two men is very well done.
My impression is that Marian Babson wrote many mysteries, but with variations in style, so I think it will be worthwhile to follow up on some of her other books. They don't show up a lot at the book sale so I shall have to make and effort to find some. (Any suggestions are welcome.)
Curt Evans at The Passing Tramp has written a couple of very informative posts with an overview of Babson's career and a focus on one of her novels.
