yeglasses. There are so many of these young men about that one
more would hardly attract Gortchky's attention. That style of dress
would make a good disguise for me."

"The young men you describe are largely students and artists," replied
the Ambassador. "A disguise of that kind would be less conspicuous
than any other."

"Then, sir, if the chauffeur can come here soon, he will have time to
take me to stores where I can get the articles of apparel I need, and
I shall still have plenty of time to meet Emil Gortchky if he reaches
Paris this evening. I will go and tell Mr. Dalzell about Gortchky
being expected to arrive here to-night."

"Tell Mr. Dalzell, if you wish, but you had better not take him with
you," replied Mr. Caine. "Two young men would attract more attention
than one. I am approving of your undertaking this because, to date,
you have learned more about this conspiracy than any three of the

"But I have the joke on you, anyway," Danny Grin suddenly declared.

"How so?" asked Dave.

"I shall have my dinner," laughed Dalzell; "you won't have any."

"I could forget my meals for three whole days to stay on the trail of

the smooth pavements of Paris, and in the well-ordered traffic,
taxicabs travel at a high rate of speed. Within five minutes he had
been set down at the door of a shop in which he found it possible to
buy every item of his disguise, even to shoes, for Darrin suddenly
remembered that his footwear was plainly American.

In fifteen minutes more Dave Darrin emerged from the store. In one
hand he carried his discarded clothing, packed in a new bag, which he
turned over to the chauffeur for safe keeping. All of his money,
except a small sum, he had left behind at the Embassy.

If any policeman had seen him enter the shop and come out again
presenting so changed an appearance, and if for that reason the
policeman should question him under the impression that Darrin might
be a spy, Dave decided that he would rely upon his chauffeur to
declare that he had been hired at the American Embassy. That s
