But it developed that the strong current of the plans of the man from Mexico ran through Valentines, that outfitter of revolutionists and dealer in second-hand and out-of-date war material. Valentines based his operations upon the principle that the discarded munitions of progressive nations are plenty good enough for use in Latin-America and that the purchase of all such, no matter how antiquated, offers a good opportunity for profit. Hardly a warlike venture in the tumultuous lands to the south has run its course within recent years without leaning heavily upon Valentines.

Knowing this, Gard was particularly anxious to find out what was transpiring within when, on a murky Saturday night, he followed the Russian and three of his Mexican associates through the narrow lanes of the lower East Side, beneath its clanging elevated, and to the side door of Valentines, within which they disappeared.

He had previously reconnoitered the surroundings. He knew that Valentines had taken great care in guarding the privacy of his establishment. The dark back room in which his conferences were held had but one entrance, which was from the main establishment. The area-way upon which its single window looked faced the wall of a printing house, broken by but three or four small windows, as is so often the case with these blank surfaces. Gard had made note of the fact that one of these windows was opposite and above that in the back room of Valentines. He had gained admission to the printing house and had viewed the adjoining premises from this high window.

A single possibility presented itself. This was that Valentines might leave his curtain up and that Jane Gates might help with the case.

Jane Gates occupied a warm spot in the hearts of the special agents and they were always particular that when they called upon her there was no possibility of unpleasant experiences, and the way seemed clear here. She was a deaf girl, known among them as the Lily Maid, born without the sense of hearing but mistress of the inestimable difficulties of lip reading and the possessor of the nimblest set of fingers in the world, these latter earning her a place as copyist for the service. Her face was of a cameo beauty, with a touch of pathos because of her isolation. She was the warm spot in the heart of the office but, as its very spirit was the untangling of riddles, she had found opportunity to help in a novel way in several difficult cases through her ability at lip reading.

By prearrangement Jane Gates, on this Saturday night, was awaiting at the office not half a dozen blocks away a possible call from Billy Gard. Barrett had a taxi at the front door and the expected summons brought him to the publishing house in five minutes. Beneath a light in the hall Gard told the deaf girl of the situation, for lip reading needs light. Soon they were in the gloom by the little window and the eager eyes of the Lily Maid were looking into the office opposite where the conference on munitions was going forward. Fortunately Valentines did not speak Spanish and an interpreter was necessary. The face of this man was in plain view not thirty feet away.

Soon Jane Gates was repeating in the peculiar, hollow voice of those who do not hear but have learned to form words with the lips:

"Mauser ammunition—old Krupp rapid-fire guns—Seventy five—"

Gard stepped beyond the range of view from the opposite window. He turned a pocket flashlight on his own lips.

"Try to find out how they are to be shipped," he instructed.
