"A good day's work," he said when I had finished; "never better. Two things are in my favour; one is that they have not got that grant yet; the other, that the three seem to be dissatisfied with their angles of the triangle. Each wants what the other has, like cats over their bowls of milk; and there is an old proverb, too, about thieves falling out, which you, no doubt, remember."

"I shall put the whole matter before the Queen, and beg her to place
Mademoiselle de Paradis in safety until this is ended."

"There is much water to flow under the bridges before this will end; but it will be a good move. The Admiral too will know of the triangle in three days; and, if I mistake not, that means that the Peace of Vaucelles is waste-paper. It will stop the Spanish pensions, at any rate for a time, and hit our vampires hard." And he chuckled as he slipped down from the coffer on to his feet. "Mon ami," he went on in his strange way, "to-night and to-morrow I shall be stirring this porridge, and by noon to-morrow you will have certain news, and then we can act. And now for your task."

"My task?"

"Yes. I knew the Queen was at the masque; she has gone there to see Diane wearing her jewels. That she will never forgive; and there will be a bitter vengeance some day—mark my words! The Queen requires the attendance of Mademoiselle de Paradis. She knows of this. It was arranged before, and she is merely awaiting the summons in the cabinet yonder, and you are to take her to the masque."

"But I have neither mask nor hood!"

"That is arranged also, and I have them ready for you. I will take mademoiselle out now, and you will meet us after your relief on the battlements outside the Philippine. You know the spot where the stairway leads from the gallery?"

"Perfectly."

"Then au revoir!" With this he slipped back into the ante-room, and five minutes after came forth, accompanied by a masked and hooded figure that would have been unrecognisable except that I knew it was Mademoiselle de Paradis.

As they came out we heard, far away in the distance, the challenge of a sentry.
