"Do you intend to arrest Miss Thorne for the shooting?" he queried.

"I don't know," replied Mr. Grimm frankly. "I don't know," he repeated musingly. "If I do arrest her immediately I may cut off a clue which will lead to the other affair. I don't know," he concluded.

"Use your own judgment, and bear in mind that a man—a man slammed the door in the maid's face."

"I shall not forget him," Mr. Grimm answered. "Now I'm going over to talk to Count di Rosini for a while."

The young man went out, thoughtfully tugging at his gloves. The Italian ambassador received him with an inquiring uplift of his dark brows.

"I came to make some inquiries in regard to Miss Thorne—Miss Isabel Thorne," Mr. Grimm informed him frankly.

The count was surprised, but it didn't appear in his face.

"As I understand it," the young man pursued, "you are sponsor for her in Washington?"

The count, evasively diplomatic, born and bred in a school of caution, considered the question from every standpoint.

"It may be that I am so regarded," he admitted at last.
