"Bring him in," he said shortly, and replaced the telephone receiver that, all this while and to the intense irritation of the exchange, he had held vaguely in his hand.

There was ushered in a lean, scarecrow figure at whose heels (despite scuffling protests from the gendarme without) limped a black, untidy dog. The tramp bowed and began at once to speak in the slow correct French of a well-educated foreigner. He told of a dusty road along which he had toiled; of a coppice and its tempting shade; of the drowsiness of afternoon; of dream voices that were not, after all, of dream; of a mound with a mysterious grating; of a subterranean cavern and its two unusual and impatient prisoners. M. Lesueur listened in silence. The story done, he took up the telephone once again. While waiting for his connection, he addressed the senior gendarme of those present in the room.

"I want the two fastest cars brought round immediately. This fellow shall take us to his mound and we will see how far he is lying and how far telling us the truth. We will then proceed to the Château de la Hourmerie. Six men will be required to accompany me. Make your selection——'allô! 'allô!—— Toussaint?—— Is that you, Toussaint?"

And he outlined with curt efficiency the instructions laid down for his subordinate.

"In an hour," he concluded, "we meet at the Château de la Hourmerie. One hour, mind you! One hour from now." Smartly and with finality he hung up the receiver.

The Commissary was already struggling into his dust coat when there came yet a second interruption. The sound of many agitated feet in the outer office prepared the occupants of M. Lesueur's private room for threatened but not for actual invasion of their retired sanctuary. Wherefore they regarded with speechless amazement the tempestuous entry of two elegantly gowned women, one clutching the other firmly by the arm, while in close and uncomfortable attendance followed two men, one tall, white-whiskered, and conspicuous in a buff alpaca suit, the other short, stout, and shining with the sweat-drops of embarrassment.

The female invaders lost no time in stating their business, but as they both spoke at once and shrilly, the unfortunate Commissary learnt little of the matter at issue between them. Not until the united efforts of all the men present had silenced feminine vociferation was it possible to understand what in the world the pother was about. The old gentleman, to whom in courtesy priority of speech was accorded, made the following statement:

"About an hour and a half ago I entered the Casino in company with the young lady whom now you observe in the grip of—er—the other lady. My companion, whose name is Amélie, was anxious at once to join the crowd at the tables.

"We contrived to edge ourselves to a convenient front seat, and for some while played quietly and with varying success. I then observed that new-comers were seeking to force a way to the front row of players, and, in order to give others their turn, stepped behind my companion, leaving vacant the spot I had previously occupied. It was filled forthwith by the second of the two ladies now before you, who thanked me with a charming smile for my courtesy, and was on the point of turning her interest wholly to the game when her eyes fell on Amélie. Instantly she flushed with excitement, paled again and flushed once more, and I was the next moment aware of a rapid movement of her arm as she snatched from the neck of Amélie an ornament that hung there from a thin gold chain.

"You can imagine the excited confusion that ensued, the outcome of which is my attendance here to account, so far as I may, for the disturbance in which I have been involved."
