Exactly at half-past seven Mr. Darlington and Canon Wilton were outside the door of Little Cloisters and Mr. Darlington pulled the bell.  Always the most discreet of men, he had not mentioned to his host the terrible cry he had heard in the Leiths’ garden, or his short colloquy with Annie.  He was seriously disturbed in mind, but, being a trained man of the world and one who prided himself upon his powers of self-control, he had concealed this unpleasant fact from the Canon, and had talked quite agreeably during their little walk between the two houses.  The sound of that dreadful cry still seemed to shudder through his flesh, but it was not for him to pry into the private lives of others, even of those whom he knew intimately, and had a great regard for.  He hoped all was well with his dear young friends, There might be some quite simple explanation of that cry.  He fervently hoped there was.  In any case it was not for him to ask questions, or to—­

“They’re a long while answering the bell,” said Canon Wilton, in his strong, earnest voice.  “Hadn’t you better give it another tug, Darlington?”

Mr. Darlington started.

“H’m—­ha!”

He raised his hand and pulled the bell a second time.

“That’s better,” said the Canon, as he heard inside the house a long tinkle.  “Annie’s bound to come now.  As a rule she’s very quick in answering the door.  Among her many virtues, Mrs. Leith counts that of being a first-rate housewife.  She trains her maids well.”

“Does she?” murmured Mr. Darlington abstractedly, bending forward till he seemed almost to be listening at the door.  “Does she?  I hear some one coming.  H’m!”

He straightened himself.  The door opened and Annie appeared.  When she saw the two men she drew back quickly to let them pass in.  Canon Wilton said kindly:  “Good evening, Annie.”

“Oh, sir,” said Annie, and began to cry audibly.

“What’s the matter?” asked the Canon, surprised.

They were now in the little oak paneled hall, and by the light of the lamp they could see the tears running down the flushed face of the maid.  “Is anything wrong?” said the Canon.

“Oh, sir, I’m so glad you’ve come!  Oh, we don’t know what it is!”

At this moment Robin’s nurse showed herself on the staircase.

“For God’s sake, sir,” she said, with trembling lips, “do go into the garden!”

“Why?” said Canon Wilton, in a loud, firm voice.

“Mr. and Mrs. Leith are both there, sir.  They’ve been there this long time.  Mr. Leith he’s come back from the shooting without Master Robin.  Oh, there’s something wrong, sir, there’s something wrong!”

“Stay here for a moment, Darlington,” said the Canon, with a sudden, almost fiery, decision.  “I’ll go at once and see what’s the matter.”

But Mr. Darlington laid a bony hand on his friend’s arm.

“I’ll come with you, Wilton.  I’m—­I’m afraid it’s something very bad.”
