Accordingly, the next morning, Pietro brought the dog up to the Park.
The animal was sullen, and would accept of attentions from no one save
Margie, to whom he seemed to take at first sight. And after she had
spoken to him kindly, and patted his head, he refused all persuasions
and commands to leave her.

Mr. Darby, the detective, whose services had been engaged in the affair,
exerted all his powers of entreaty on the dog, but the animal clung to
Margie, and would not even look in the direction of the almost frantic
detective.

"It's no use, Miss Harrison," said Darby, "the cur wont stir an inch. You
will have to come with him! Sorry to ask ye, but this thing must be seen
into."

"Very well, I will accompany you," said Margie, rising, and throwing on
a shawl, she went out with them, followed by Mrs. Weldon, Alexandrine,
and two or three other ladies.

Leo kept close to Margie, trotting along beside her, uttering every now
and then a low whine indicative of anticipation and pleasure.

Darby produced a handkerchief which had belonged to Mr. Paul Linmere,
and which he had found in his rooms, lying on his dressing-table. He
showed this to the dog; Leo snuffed at it, and gave a sharp grunt of
displeasure.

"We want you to find him, Leo, good dog," said the Italian, stroking the
silky ears of the dog; "find your master."
