Instantly the man was put to the test.

“Open, and act as thou wouldst have done were I not here,” he muttered. He and Devi Pershad, with the Rajputs of the first guard, hastened into the dark interior of the lodge while the man unbound the gate. There entered a very harmless couple, a bhisti, carrying his empty water-bag of goatskin, and a veiled woman whose simple garb showed that she was of the same caste, in all probability his wife.

But why had such a pair used a password, and why were two different passwords in vogue at all that night? Here was a minor riddle of which a sword-point might find the key. Walter sprang forth and seized the water-carrier. The woman uttered a slight cry of alarm, but seemed to regain instant control of herself. The poor bhisti was so taken aback by the sight of the gleaming blade with which the Englishman enforced his stern demand for information that he uttered not a word. His jaw fell and he gazed up at Walter in dumb fear.

Somehow, when the rays of the lantern revealed his features, Mowbray thought he knew the man. Suddenly, recollection came. This was the palace servant who warned him and Roger against Jahangir’s malice on the day of the wild beast combats.

But, whatever form Mowbray’s questions might have taken, all such speculations were driven from his brain, and he released the bhisti in blank amazement, when a well-remembered voice murmured sweetly:—

“Harm him not, Walter. He is a humble well-wisher who escorted me hither.”

It was Nur Mahal who spoke. Never before had she addressed him by his Christian name, the sound of which she must have learned owing to Roger’s frequent use of it. Clearly, she had acquired its facile pronunciation by much private endeavor, for his own mother could not have uttered the word more accurately.

And what was he to say, or do? Though it was always a likely thing that Nur Mahal, knowing he was in Agra, would endeavor to reach him, now that she was actually here how should he shape his course to avoid the complications sure to result if her visit came to Jahangir’s ears? It is not to be wondered at if his brain whirled with jostling thoughts, nor that her presence should obscure for the nonce the vital importance of ascertaining the significance of the passwords, whose mere choice showed that they represented the rival factions of Mahomedans and Hindus.

“I see that you are not to be taken by surprise, let those plan who will,” she whispered, and she laughed musically, with a certain frolicsome lightness long absent from her manner. Was the winsome maid of the Garden of Heart’s Delight re-born amidst the sorrows which encompassed her? Was her rapid descent from high estate the means of her regeneration, seeing that content oft arrives by the door through which ambition departs? Who could tell? Certainly not Mowbray, to whose already grievous load of cares her presence added no inconsiderable charge.
