“What boy?”

“The one who asked me if I was too rich and proud to play with him.  And that must be his sister; they look alike.”

“All right,” said Scott; “we’ll give them a volley.  You take the nurse and I’ll fix the boy....  Ready....  Fire!”

The ambuscade was perfectly successful; the nurse halted and looked up, expressing herself definitely upon the manners and customs of the twins; the boy, who appeared to be amazingly agile, seized a swinging wistaria vine, clambered up the wall, and, clinging to the outside of the iron railing, informed Scott that he would punch his head when a pleasing opportunity presented itself.

“All right,” retorted Scott; “come in and do it now.”

“That’s all very well for you to say when you know I can’t climb over this railing!”

“I’ll tell you what I’ll do,” said Scott, thrilled at the chance of another boy on the grounds even if he had to fight him; “I’ll tell you what!” sinking his voice to an eager whisper; “You run away from your nurse as soon as you get into the Park and I’ll be at the front door and I’ll let you in.  Will you?”

“Oh, please!” whispered Geraldine; “and bring your sister, too!”

The boy stared at her knickerbockers.  “Do you want to fight my sister?” he asked.

“I?  Oh, no, no, no.  You can fight Scott if you like, and your sister and I will have such fun watching you.  Will you?”

His nurse was calling him to descend, in tones agitated and peremptory; the boy hesitated, scowled at Scott, looked uncertainly at Geraldine, then shot a hasty and hostile glance at the interior of the mysterious Seagrave estate.  Curiosity overcame him; also, perhaps, a natural desire for battle.

“Yes,” he said to Scott, “I’ll come back and punch your head for you.”

And very deftly, clinging like a squirrel to the pendant wistaria, he let himself down into the street again.

The Seagrave twins, intensely excited, watched them as far as Fifth Avenue, then rapidly drawing on their shoes and stockings, scrambled down to the shrubbery and raced for the house.  Through it they passed like a double whirlwind; feeble and perfunctory resistance was offered by their nurses.

“Get out of my way!” said Geraldine fiercely; “do you think I’m going to miss the first chance for some fun that I’ve ever had in all my life?”

At the same moment, through the glass-sheeted grill Scott discovered two small figures dashing up the drive to the porte-cochere.  And he turned on Lang like a wild cat.

Lang, the man at the door, was disposed to defend his post; Scott prepared to fly at him, but his sister intervened: 

“Oh, Lang,” she pleaded, jumping up and down in an agony of apprehension, “please, please, let them in!  We’ve never had any friends.”  She caught his arm piteously; he looked fearfully embarrassed, for the Seagrave livery was still new to him; nor, during his brief service, had he fully digested the significance of the policy which so rigidly guarded these little children lest rumour from without apprise them of their financial future and the contaminating realisation undermine their simplicity.
