investigation of the shooting affair to another man," said Mr. Grimm
emphatically, reverting to his chief's question. "I think, on the
contrary, we should find out more about Miss Thorne."

"Precisely," Campbell agreed.

"Ask all the great capitals about her--Madrid, Paris and Rome,
particularly; then, perhaps, London and Berlin and St. Petersburg."

Mr. Campbell thoughtfully scribbled the names of the cities on a slip of
paper.

"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.
