Barzun and Taylor (A Catalog of Crime) on The Widening Stain (1942) by W. Bolingbroke Johnson (pseud. of Morris Bishop): “An academic double murder in a library, solved by the semiyoung librarian heroine. The relationships are well drawn, but there are few physical clues and not enough sound work on the space-and-time question. What makes the book delightful is the witty narration, dialogue, and interspersed limericks.”
