American writer (1903–1968) who is best known for his crime fiction; his story It Had to Be Murder served as the source for Alfred Hitchcock's 1954 classic Rear Window. TLS, one page, 6 x 9, Hotel Marseilles letterhead, November 11, 1946. Letter to literary agent H. N. Swanson, in part: "On Saturday Nov. 9th, the Camay Program, over CBS…presented Michele Morgan and Robert Cummings in a radio adaptation of The Chase. Seymour Nebenzal, the producer of that picture, also spoke on the program. This picture, The Chase, is based on my novel The Black Path of Fear. It was bought from me by the King Brothers, and later resold by them to Nebenzal. I want you to notify Nebenzal that I control radio rights to Black Path of Fear, that I did not grant permission for this radio performance of it, that I don't want it to be repeated, and that I expect my customary share of the fee that was paid for this particular performance. You will of course deduct your commission from whatever amount is involved." In fine condition, with staple holes to the upper left corner, and a short tear to the top edge.
