'You are a man, Ambrose,' she declared. 'Do not be afraid. We are allies, is it not so?'

'In this, yes!' he promised her....

Two hours later, as they moved slowly down the river, the tugs shrieking in front of them, and siren whistles blowing on every side, they examined for the first time, in the security of Lavendale's state-room, their new treasures—the black, camera-like instrument, the smaller one, with its dial face, and a little skein of the white, silk-covered wire. They both gazed at them almost in stupefaction—harmless-looking objects, silent, dead things.

'Only think,' she whispered, clutching his arm, 'we have but to learn their secret and we can end the war!'

Lavendale hid them away and silently they stole up on deck. They heard the engines quicken their beat, saw the great buildings of the city fade into an evening mist. They saw the lights shoot out from the Statue of Liberty and felt the ocean breeze on their cheeks. They turned their faces eastwards. The apprehension of great things kept them silent. They faced the Unknown.

CHAPTER IX
AN INTERRUPTED REVUE

Madame Félanie sat before the gaily-decorated mirror which swung upon her dressing table, contemplating the result of her maid's careful and strenuous attentions. Her dressing-room, during the many months of her great success, had become transformed into a little bower of luxury and comfort. A telephone stood at her elbow amongst a chaos of tortoiseshell-backed toilet articles. There was a soft green carpet upon the floor, a wonderful divan in the most comfortable corner, a few trifles of Empire furniture, an etching or so upon the wall. Madame Félanie was a clever woman and she understood the art of environment.

Her costume now for the second act of the brilliant revue in which her success had been almost phenomenal, was practically completed. She wore still a rose-coloured dressing-gown over garments not remarkable for their prodigality, and though the evening papers, a French novel, a little volume of poetry sent from the author, and a box of Russian cigarettes stood at her elbow, she still continued to gaze a little abstractedly at the reflection of her own features in the looking-glass. London had found her beautiful, seductive, vivacious. She was all of these. Her dark and beautifully-set eyes restrained their gleam of natural violet notwithstanding the encompassment of stage make-up. No rouge could conceal the pearly brilliancy of her complexion, no cake of powder the charming lines of her mouth. It was not at these things, however, that she looked. Her eyes were fixed steadily upon the roots of her blue-black hair, drawn back from her forehead in a manner peculiar to herself. She even raised the tiny magnifying glass on the table before her, to concentrate her regard, and there was in her face almost at that moment a shadow, as though some faint foreboding was hovering over her, even in these halcyon days of her great triumph.

She laid the magnifying glass down.
