Patrcia Wentworth--and Milton Caniff?
A friend sent me this link to a Fifties website. Here we find a Patrcia Wentworth mystery novel serialized in a newspaper and illustrated by Milton Caniff. You can enlarge the pages for a closer look at both the copy and the art. Wentworth was a very popular mystery writer and Caniff a master innovator in daily comics and comic books. Interesting to see that he didn't use his famous noirish inking style (Terry & The Pirates etc,) for this assignment but instead went to a more open approach. This may have had to do with newspaper mechanics.
