"A bright blue roadster, low-swung and smart, rolled swiftly along the winding lake road to halt suddenly before a large signboard which boldly proclaimed to all who chanced that way:
LILAC INN: CHICKEN DINNERS OUR SPECIALTY.
The driver, a pretty girl of perhaps sixteen, attractive in a frock which either by accident or design exactly matched the blue of the automobile, smiled whimsically as she read the words."
