For example, are you thinking of:
* Norman Douglas, a British novelist known for his witty and often scandalous prose, like in "South Wind"?
* Lloyd Douglas, an American novelist best known for his historical novels like "The Robe" and "The Big Fisherman"?
* Stephen Douglas, a renowned American politician, who was known for his powerful and persuasive speeches, rather than written works?
To give you a helpful answer, please specify which "Douglas" you are interested in. Once you tell me who you mean, I can provide information about their writing style.
