The nearest man approached the heap and began to shake it out.

‘I’ll gi’e ye a lift up, Robbie,’ said one of the voices; ‘there’s stanes stickin’ out o’ the wa’ at the west side. I had a richt look at it Sabbath last when the kirk was in.’

‘My! but you’re a sinfu’ man!’ exclaimed Robbie.

‘We’re a’ that,’ observed a third speaker piously.

Two of the men took the net, and went round the dovecot wall till they found the stones of which their companion had spoken; these rough steps had been placed there for the convenience of anyone who might go up to mend the tiling.

‘Lie still till they are both up,’ whispered Gilbert. ‘There are two to hold the net, and one to go in and beat out the birds.’

They crouched breathless in the broom till they saw two figures rise above the slanting roof between them and the sky. Each had a length of rope which he secured round one of the stone balls standing at either end above the crowsteps; it was easy to see that the business had been carefully planned. Inside the dovecot, a cooing and gurgling showed that the birds were awakened.

The two men clambered down by the crowsteps, each with his rope wound round his arm and supporting him as he leaned over to draw the net over the pigeon-holes.

‘Now then, in ye go,’ said Robbie’s voice.

The key was in the door, for the third man unlocked it and entered.
