Excerpt
The three friends had made for this part of the resort as soon as they had arrived.

Randy was quite as much interested in peering in at the windows of the few buildings bearing “To Rent” signs. Pep made a deliberate stop wherever a show place attracted his attention. Now all three had halted in front of an unoccupied building and were looking it over critically.
