From a pioneer of the medieval mystery:
The Trinity Cat and Other Mysteries is a collection of fifteen tales of mystery by Ellis Peters (1913-1995) most of which were written before a certain Benedictine made her rich and famous and one story of which is published here for the first time anywhere.
The cat, alas, does not belong to our beloved Brother Cadfael
