The author of a book that tells the story of one of the most tragic events in Hannibal’s history will be in town Saturday.

John Wingate will be at the Mark Twain Museum Gallery auditorium at 2 p.m. to discuss his book, “Lost Boys of Hannibal: Inside America’s Largest Cave Search.”

It’s the story of Joel and Billy Hoag and Edwin Craig Dowell, three young boys who went exploring in an underground cave system on the south side of Hannibal in May of 1967 and were never seen again.

Wingate tells the story of the boys and the month-long search that brought cavers from all over the world to Hannibal to help in the search.

Copies of “Lost Boys of Hannibal” will be available for sale Saturday in the Mark Twain Museum gift shop.
