"It is I, Miss Hannay--Bathurst. Danger threatens you, and you must escape at once. Rabda is waiting for you outside. Please go to the door and stand there until I open it. I have no doubt that I shall succeed, but if anything should go wrong, go and lie down again at once."

Without waiting for an answer, he moved towards the fire.

"Is that you, Ahmed?" one of the warders said. "We all seem sleepy this evening, there is something in the air; I felt half inclined to go off myself."

"It is very hot tonight," Bathurst replied.

There was something in his voice unfamiliar to the man, and with an exclamation, "Who is it?" he sprang to his feet. But Bathurst was now but three paces away, and with a bound was upon him, bringing the tulwar down with such force upon his head that the man fell lifeless without a groan. The other two leaped up with shouts of "Treachery!" but Bathurst was upon them, and, aided by the surprise, cut both down after a sharp fight of half a minute. Then he ran to the prison door, turned the key in the lock, and opened it.
