Former President Bill Clinton and author James Patterson came to Scarsdale Tuesday to sign copies of their new novel.

The pair appeared at the Barnes & Noble Eastchester in Scarsdale to sign “The President is Missing.”

More than 500 copies of the book were sold at the store, which set a record.

The book is about the fictional disappearance of a U.S. president after a cybercrime attack jeopardizes Secret Service protection, something Clinton says he was leery about at first.

Fans of the former president came to the store as early as 5 a.m. to wait for a chance to get in.
