"It may be," Karl replied, apparently much astonished at this clear reasoning. "It may be. Therefore, you had three visitors on that night."

"I cannot say. I have but proof of two. The wearers of the two hats at least were here. Yet they may well have been the only visitors; in solemn truth there may not have been three. Though strange it is that, if there were but two, both should have parted with their hats. One must have lost his in the encounter in which he received his death-wound, the other in fleeing away."

For, now, Bevill had grave doubts as to whether Francbois had been at the Weiss Haus at all on the night before the one now past. Still, if it were not Francbois who had mortally wounded Sparmann--while almost of a certainty supposing Sparmann to be another person, namely, himself--who was it? Who was the other enemy he possessed? He knew neither of personal enemy nor spy tracking him, nor of French soldier or official likely to do so.

All the same, there was, there must be, a third enemy, even though Francbois had not been of the number that night, since it was almost certain that neither of those hats would have been worn by him--even as a disguise. There must be two others beside him while Sparmann was alive!

"And still there is more mystery," Bevill mused as the old man stood gazing up at him, "more that is inexplicable. Sparmann did not find his way out through either of the doors, nor, since I followed him as he fled down the stairs, did he do so by the ladder against the balcony. How, then, did that come to pass? Did he hide somewhere in the house until I had opened the door leading to the stables, or was there some window near the ground through which a man wounded to the death might yet escape?"

But no answer came to these reflections. Whatever had taken place in the Weiss Haus, other than all which he already knew, had left no trace behind.

Ten had struck, and, next, the quarter, from all the city clocks ere Bevill had concluded these reflections, and still the carriage which he was to accompany to the gate (since, as has been told, it was finally decided that all should leave the city together, or attempt to leave it) had not appeared.

As, however, the half-hour rang out, Bevill perceived it drawing near. On the box he recognised Joseph, he being, doubtless owing to the necessity for a coachman, the only servant whom the Comtesse de Valorme had thought fit to bring with her.

Slowly the carriage drew near until, now, it was almost abreast of where Bevill sat his horse, when, allowing La Rose to advance, he rode up to the side of it and, bowing low to its occupants, asked if all was well with them.
