7/24/1915 Baby blue for the onesie

July 24, 1916.  This was the birthday of one of the most popular and prolific of American mystery writers, John D. MacDonald.  He is best remembered as the creator of "salvage expert" Travis McGee, but his other work included the novel The Executioners, filmed twice as Cape Fear.

The Mystery Writers of America named him a Grand Master in 1972. Or should we say they recognized him as one?
