There was no response to his knocking, which he repeated at intervals far several minutes. Then he called aloud the name of his princess, to be answered only by silence. M. Klein became more and more perturbed in spirit. He still hesitated to turn the knob and enter the apartment of her royal highness without first obtaining permission, but at last he grew desperate. The knob turned beneath his fingers, he pressed outward with increasing vigor, but the door did not open-M. Klein was a prisoner. It came to him with the sudden shock of an unexpected douche of cold water; and it made him tremble all over and gasp, too, as the water might have.

For a moment or two he stood looking dumbly at the blank panels of the door. Knowing the Princess Mary as he did he was quite positive that his imprisonment was not a matter of chance; but what would the king say! At the thought M. Klein went white, and commenced to beat violently upon the door, shouting in the mean while at the top of his voice. There was no response.

The afternoon waned, and darkness came. M. Klein was exhausted by his vain efforts at attracting attention. The little, grated window had proved too high for him to reach, and' had only served to admonish him of the flight of time as the afternoon light which it shed within his tiny prison waned and, faded into the blackness of night.

The secretary became frantic. His calls for help rose finally to wild shrieks. He pounded upon the door. He kicked it, and continually he cursed himself for a silly ass in thus permitting a slip of a girl to put him in so ridiculous and dangerous a position. The king would never forgive him-he would be lucky if Alexis did not throw him into prison.

For the twentieth time he leaped for the grating of the window above him. His fingers caught and held. He drew himself up until his face was at the opening, and then he opened his mouth and gave vent to a piercing scream for help.

Below in the courtyard a sentry pacing to and fro heard the wild cry. Instantly his own voice rose in a sharp summons for the non-commissioned officer of the guard. The scream from above was repeated as a sergeant came upon a run from the guard house.

"Who calls?" cried the sentry.

M. Klein's fingers were relaxing their hold upon the grating. He had only time to cry: "Princess Mary's apartments!" before they slipped and let him drop back to the floor of his prison.

But the sergeant had heard, and so had the sentry; and a moment later an officer of the guard followed by a score of armed men were dashing through the corridors of the- palace, up stairs, and along passageways until they came to the suite of the Princess Mary.

And here they permitted no courtly etiquette to detain them, but throwing open the doors bolted into the forbidden precincts of the royal apartments. A moment later M. Klein was released and, bundled into an automobile, was speeding toward Klovia, his heart in his mouth and his brain a-whirl with the stupendous fact that the Princess Mary had fled the royal palace.

At about the same time Stefan, mounted upon the abandoned horse of the highwayman, was spurring along the Roman road into Demia. Through the streets of the ancient capitol he raced, regardless of gendarmes and speed laws, upon his way to Klovia and his king.

Alexis III, relieved of the embarrassment of his royal guest, was giving himself over to the pleasures of the society of his own nobility, when a very much excited and dishevelled young man dashed unannounced into the banquet hall, throwing aside and upsetting a couple of guardsmen who had thought to interrupt his impetuous progress. To the king's side the young man made his way, while the guardsmen, picking themselves from the floor, pursued him.

"Klein!" exclaimed the king. "What is the meaning of this?"

"O, pardon, Sire!" cried the excited secretary, falling upon his knees. "It is awful!"

"What is awful?" demanded the king, rising.

The guests too rose from their seats.
