The Dreadful Lemon Sky (1975) is the sixteenth novel in the Travis McGee series by John D. MacDonald.

Carrie, an old friend of the hero, Travis McGee, arrives at his houseboat, the Busted Flush.

His investigation leads him to an apartment complex full of singles presided over by a landlord called 'Big Daddy'.

The bleared sun made harsh studio lighting on the parking lot scene.

And Harry Hascomb saw Captain Scorf's horrid death under the dreadful lemon sky.The book does not make an indication of whether McGee relayed the illicit money to Carrie Milligan's sister or how much he kept for himself.
