But the trooper’s suspicions were thoroughly roused now, and he jumped for the door. Darby caught him by the skirt of his coat in passing and swung him back violently. The trooper’s hand went to his hip, but Darby’s hand went to his and took a grip. And what Darby gripped usually held still. The trooper recognised this, but he made a desperate effort to free himself. Darby twirled him round and threw his arms round him, pinning the trooper’s arms rigidly to his side.

The trooper could use his tongue if he could use nothing else, and he did so with fluency and effect. But Darby held him till a total of ten minutes was gone, and then quietly released him.

The trooper faced him with another burst of language and a heavy revolver pointing in his face. “What—d’you mean?” he demanded.

“It’s orright,” said Darby. “I’ve showed you something, an’ I’ve persuaded you to stay five minutes. It’s orright. You can go now,” and he waved a huge hand towards the open door.

The trooper sprang through it, but was back in a few minutes. “Where’s yer mate gone, blast ye?” he shouted.

“Gone for a moonlight ride wi’ the gal,” said Darby, soothingly. “They’ll be back by’n’bye. You wouldn’t want to go runnin’ after a young couple that way, would you? And besides,” he added, “I dessay Ned shoved the ’orses to the back end o’ the paddock while ’e was at it. But go’n catch yours if you want to. In fac’, I’ll ’elp if you like.”

But the trooper had had enough of Darby’s assistance. “You’ll hear suthin’ more o’ this,” he said viciously. “I suppose you know what you stand to get for interferin’ wi’ a constable in the execution o’ ’is duty.”

“No,” said Darby, with interest. “Tell me. An’ tell me wot was the duty—an’ I didn’t execute you any,” he shouted after the trooper as he hurried out and down in the direction of the horse paddock. “An’, hi you!” he yelled into the darkness, “’adn’t you better come back an’ tidy up that straw you spilt?”

In the meantime Ned and Ess had made good use of the start Darby had given them, and they rode forward in silence at a hard canter. The moon made the track clear to be seen, and Ned Gunliffe rode well in advance. Ess rode with a mind whirling with doubts, anger with Ned and with herself, with fears—fears for herself and for Steve—and, worst of all, with a dreadful and sickening apprehension of what she was going to see.

They rode steadily till they came to the spot from which Ned had first seen the light, and he pulled up there and slid to the ground. “Can you dismount, or shall I help you?” he asked smoothly. Ess was riding across-saddle, and she caught her divided skirt up on the off side and swung neatly to the ground without answering.
