But Jessie was resolved to frustrate that. She stepped quickly forward and hailed the other cab. Then for the first time she saw that the newcomer was not, as she expected, a man, but a woman. She was tall and fair, and exceedingly good looking.

"I particularly want that cab," she said coolly. "I put up my hand first."

The speaker used good English, Jessie noticed, though with a lisp. Without waiting to combat the point, Jessie jumped into the cab.

"There is another a little way down the lane," she said. "I am in a hurry, or I would wait. Please drive me to 14, Albert Mansions, Hyde Park."

With a sort of smothered exclamation, the other hurried down the lane. The cabman again asked where he was to go. He had not caught the direction, he said.

"I don't want to go anywhere," Jessie said coolly, as she came to the ground again. "Take this half sovereign, and drive some distance, say a mile, at a good pace. And if you can possibly prevent that woman behind catching the first cab so much the better. Now bang your doors to and be off."

With a grin the cabman touched his cap, the door banged, and the hansom set off as if the fare were in a breakneck hurry. Standing well back in the doorway Jessie had the satisfaction of seeing the fair woman flash by her presently on her futile errand. She had saved the situation for the present. Nobody guessed where the King of Asturia was, and the spy had gone off on a false errand altogether. No doubt the would-be assassin had departed by this time.

In a fever of impatience Ronald Hope awaited Jessie at the steps of the balcony. The gardens were quite deserted by this time, so that it was possible to talk in safety.

"He got clear off," Jessie said, not without a little pardonable pride. "As I expected, an attempt was made to follow him, only fortunately there were only two hansoms in the lane, and I took the second one and pretended to drive away whilst the spy was hurrying elsewhere in search of a conveyance. That was what I wanted your half sovereign for, Ronald."

"And the spy?" Ronald asked. "What sort of a fellow was he?"
