Evidently Richard knew the red-headed man, for he crossed over to him at once with the words:

"I guess this is for you, Mr. Atkins?"

He handed him the despatch and retired. The red-headed man signed the receipt; the boy departed. Blix and Condy heard the sound of torn paper as the red-headed man opened the telegram.

Ten seconds passed, then fifteen, then twenty. There was a silence. Condy dared to steal a glance at the red-headed man's reflection in the mirror. He was studying the despatch, frowning horribly. He put it away in his pocket, took it out again with a fierce movement of impatience, and consulted it a second time. His "supper Mexican" remained untasted before him; Condy and Blix heard him breathing loud through his nose. That he was profoundly agitated, they could not doubt for a single moment. All at once a little panic terror seemed to take possession of him. He rose, seized his hat, jammed it over his ears, slapped a half-dollar upon the table, and strode from the restaurant.

This is what the read-headed man had read in the despatch; this is what Blix had written:

"ALL IS DISCOVERED. FLY AT ONCE."

And never in all their subsequent rambles about the city did Blix or Condy set eyes upon the red-headed man again, nor did Luna's restaurant, where he seemed to have been a habitue, ever afterward know his presence. He disappeared; he was swallowed up. He had left the restaurant, true. Had he also left that neighborhood? Had he fled the city, the State, the country even? What skeleton in the red-headed man's closet had those six words called to life and the light of day. Had they frightened him forth to spend the rest of his days fleeing from an unnamed, unknown avenger—a veritable wandering Jew? What mystery had they touched upon there in the bald, bare back room of the Quarter's restaurant? What dark door had they opened, what red-headed phantom had they evoked? Had they broken up a plot, thwarted a conspiracy, prevented a crime? They never knew. One thing only was certain. The red-headed man had had a past.

Meanwhile the minutes were passing, and K. D. B. still failed to appear. Captain Jack was visibly growing impatient, anxious. By now he had come to the fiery liqueur called mescal. He was nearly through his supper. At every moment he consulted his watch and fixed the outside door with a scowl. It was already twenty minutes after seven.

"I know the red-headed man spoiled it, after all," murmured Blix. "K. D. B. saw the two of them in here and was frightened."

"We could send Captain Jack a telegram from her," suggested Condy. "I'm ready for anything now."
