Wyatt’s eyes dilated with the suspicion he felt, and his face looked harder and sterner than ever as he replied:

“Captain Hulton is still an invalid, sir, and Doctor Robson has nothing whatever to do with the conduct of our troop. I am in command, and the matter concerns me, and the honour generally of the troop. Mr Darrell, our young officer, has suddenly disappeared; I ask you and yours for some explanation, and I am told that it is a matter concerning our honour; have the goodness to tell me what you mean.”

There was again a low murmur and fierce gesticulations amongst the officers, who resented Wyatt’s tone, for he was speaking to the Rajah as if he were the offender being called upon to explain.

The Rajah sat troubled and stern for a few minutes as if irresolute, while the Wazir and other officers whispered together in a way which made Wyatt feel that his life was hanging, as it were, upon a thread.

“It is most painful, and a sorrow to me,” said the Rajah at last, “for I have behaved to this Mr Darrell as if he were my friend.”

Wyatt nodded shortly.

“He has come and gone here as he pleased, and my mother has during the past month treated him as if he were a son.”

Wyatt nodded again.

“He has been as free to go to and from her apartments as I have, and in opposition to the custom of our people, for she has often laughingly said he was but a boy.”

“Well, sir,” said Wyatt sternly, “what has this to do with the disappearance of my brother-officer?”
