The spirit of phantasy embraced me; and, unmoved to further surprise, I watched the unknown swarm down the ladder with the agility of an ape. He seemed to wear a robe, surely that of the Veiled Prophet! He silently manipulated one of the side-panels of the window, opened it, and vanished within the Harêm Suite.

Raising my eyes, I beheld a second figure—that of Abû Tabâh—descending a similar ladder to the balcony of Inspector Carlisle’s room. He gained the balcony and entered the room. Four seconds elapsed; he reappeared, unfurled a greater length of ladder, and came down to the flower-beds. Lithely as a cat he came to the projecting mushrabîyeh, swung himself aloft, and as I watched breathlessly, expecting him to enter in pursuit of the intruder, climbed to the top and began to mount the ladder descending from Major Redpath’s room!

He had just reached the major’s balcony, and was stepping through the open window, when a most alarming din arose in the Harêm Suite; evidently a fierce struggle was proceeding in the apartments of the Mudîr’s daughter!

I scrambled down from the acacia and ran to the spot immediately below the window, arriving at the very moment that the central lattice was thrown open, and a white-veiled figure appeared there and prepared to spring down! Perceiving my approach:

“Oh, help me, in the name of Allah!” cried the woman, in a voice shrill with fear. “Quick—catch me!”

Ere I could frame any reply, she clutched at the palm tree and dropped down right into my extended arms, as a crashing of overturned furniture came from the room above.

“Help them!” she entreated. “You are armed, and my women are being murdered.”

“Help, Kernaby Pasha!” now reached my ears, in the unmistakable voice of Abû Tabâh, from somewhere within. “See that he does not escape from the window!”

“Coming!” I cried.

And, by means of the palm trunk, I began to mount towards the open lattice.
