Martin is aloof, dressed in a suit and way too proper for the other campers. He greets them with, "How do you do, gentlemen?" He is more than happy to let Mr. Burnett carry his luggage to the bunk house and wonders why he can't have a private room. He winces when Burnett calls him Marty, not Martin. When Bill asks Marty about what sports he likes, he replies no to all of them. He does have a collection of books about horses that he brought along, although he admits to having never been on a horse. The other boys feel a bit sorry when they learn he has no parents. Camp director Logan tell Burnett that Marty's dad was one of his military officer pals who was killed in action during WWII.
