Daniel, Eugene Friedman talk about Sherlock Holmes and 'Doyle's World'

The game is still afoot. In the case of Arthur Conan Doyle, whose Sherlock Holmes stories still intrigue, puzzle and surprise readers, new clues await revelation.

You’ll find them in “Doyle’s World — Lost and Found: The Unknown Histories of Sherlock Holmes and Sir Arthur Conan Doyle” (Square One, $29.95), a new study by father-son authors Eugene (dad) and Daniel (son) Friedman. Eugene of Dix Hills and Daniel of Miller Place, who are pediatricians in Floral Park, will be at The Next Chapter in Huntington on Nov. 16 to talk about the book, which follows an earlier volume they wrote (“The Strange Case of Dr. Doyle") and emphasizes hitherto unknown aspects of Doyle’s early years and their connections to his stories. Also included in the volume are two charming Holmes stories that had been published under pseudonyms.

The Friedmans talked recently to Newsday about their work as literary detectives.

How far back goes your fascination with Doyle and Holmes?

How did your interest in Watson and Holmes lead to writing a book about them and how did the work become a father-son project?

Doyle practiced medicine, the two of you practice medicine and, as you’re aware, the shelves are lined with mysteries solved by medical practitioners. What links medicine and detection?

In writing the book, did you do any detecting of your own?

How did you find time to write while serving full time as medical practitioners? And what were your working methods as a team?

Much has been written about Doyle. What does your book bring to the table?
