To help me find the right author, could you please provide more information about:
* What kind of books does he write? (Fiction, non-fiction, specific genre like thrillers or historical novels?)
* Are there any specific titles you've heard of?
* Is he known for a particular area of expertise?
* Is there any information about his nationality or any other identifying details?
Once I have more information, I can help you find the right David Berenson and his works.
