Big Bob grumbled. Delay irked his soul.
“All right, you old grumbler,” laughed Frank. “Come on, I’ll give you some action. We have several hours of good daylight left before dinnertime. I’ll take you on at tennis. Della and I will play you and Jack, and we won’t give you time to worry about anything.”
Della was Bob’s sister, two years younger than he. Frank, whose parents were dead and who lived with the Temples, referring to Mr. Temple, his guardian, as “Uncle George,” was very fond of her. The others joshed him about Della frequently. Bob took occasion to do so now, as the three walked away from the hangar toward the Temple home and tennis courts.
“Huh,” he said, “you’ll be looking at your partner so often you won’t be able to play. Why, you won’t even be good practice for Jack and me.”
CHAPTER III
THE HAUNTED HOUSE
Della was lithe-limbed, quick of eye and strong of wrist, a born tennis player. As for Frank, tennis was the one sport at which he could excel his chums. The result was that, despite the strong game played by Jack and Bob, Frank and Della won two sets, 7-5, 8-6.
Mr. Hampton appeared on the scene when the second set stood at six-all, bringing with him an alert, thin-faced man of middle age, clad in the uniform of a colonel in the United States Engineers. Mr. Temple with his wife emerged from the house to greet their guests, and all four were interested spectators of the two concluding games which were bitterly contested, went to deuce a number of times, but finally were won by Della and Frank.
