“But you promised not to go out alone,” said Mike, at once. All the children thought the world of their promises and never broke one.

“Well, I shan’t be alone — I shall be with Ranni and Pilescu, and they won’t know it!” grinned Jack, quite good-tempered again now that he had thought of a way to join in the adventure. For adventure it had become, there wasn’t a doubt of that!

The others laughed. It was quite true. Jack would certainly not be alone!

So, that night, after they had gone to bed, Jack kept his ears pricked to listen to any sounds of Ranni and Pilescu leaving. The moon swam up into the sky and the mountain-side was as light as day. The boy suddenly heard the low voices of the two Baronians, and he knew they were going down the passage to make their way to the great front door.

He had not undressed, so he was ready to follow them. After them he went, as quietly as a cat. The others whispered to him:

“Good luck!”

“Don’t let Ranni see you or you’ll get a spanking!”

“Look after yourself, Jack!”

The big front door opened, and shut quietly. Jack waited for a moment, opened it, and crept after the two men. He had to be careful to keep well in the black shadows, for it was easy to see anyone in the moonlight.

Up the mountain track behind the castle went Ranni and Pilescu. They did not speak, and they made as little noise as they could. They kept a sharp look-out for any sign of the robbers, but there was none. Word had come to the castle that evening that a company of local people, returning from market, had been set upon and robbed that afternoon, and the two Baronians had no doubt that the robbers were the men that Jack had seen in the cave.
