"His duty, I suppose," said Hafiz.

"His duty to what—his Commander or his conscience?"

"If a soldier is under orders I suppose he has no conscience?"

"I wonder!" said Gordon, and promising to write to Hafiz in the morning, he went up to his quarters.

The room was in darkness, save for the moonlight with its gleam of mellow gold, which seemed to vibrate from the river outside, and Gordon stood by the window, with a dull sense of headache, looking at the old Nile that had seen so many acts in the drama of humanity and still flowed so silently, until he became conscious of a perfume he knew, and then, switching on the light, he found a letter in a scented envelope lying on his desk. It was from Helena, and it was written in her bold, upright hand, with the gay raillery, the passionate tenderness, and the fierce earnestness which he recognised as her chief characteristics:—

"MISTER, most glorious and respected, the illustrious Colonel Lord, owner of Serenity and Virtue, otherwise dear old Gordon—

"It was wrong of you not to come to dinner, for though Father over-excited himself at Ghezirah to-day and I have had to pack him off to bed, I made every preparation to receive you, and here I am in my best bib and tucker, wearing the crown of pink blossom which my own particular Sultan says suits my gipsy hair, and nobody to admire it but my poor little black boy Mosie—who is falling in love with me, I may tell you, and is looking at me now with his scrubby face all blubbered up like a sentimental hippopotamus.

"I am not surprised that the Consul-General talked about the new 'holy man,' and I do not wonder that he ordered you to arrest him, but I am at a loss to know why you should take counsel with that old fossil at El Azhar, and you can tell Master Hafiz I mean to dust his jacket for suggesting it, knowing your silly old heart is like wax, and they have only to recite something out of the 'noble Koran' and you'll be as weak as—well, as a woman.

"As for holy men generally, I agree with the Princess that they are holy humbugs, which is the title I would give to a good many of the genus at home as well as here, so I say with your namesake of glorious memory (who wasn't an ogre, goodness knows!), Smash the Mahdi!

"A thousand to one he is some ugly, cross-eyed old fanatic, who would destroy every germ of civilisation in Egypt and carry the country back to barbarity and ruin, so I say again, Smash the Mahdi!
