Dick did not reply; he was not sure whether he ought to name him.

But Johnnie Naylor, who with his brother was present, exclaimed—

"George Bentham is his enemy, I think, for he said the other day he hated Dick, because he was put over him about the windows just because he was a favourite."

A new idea appeared to strike Mr Naylor. He seemed in deep thought for a moment. He was thinking of the noise he fancied he had heard. Then taking down a lantern and lighting the lamp within, he strode off without a word, and took his way to the greenhouse.

Unlocking the door, he entered, and closed it after him. Again there was a slight noise. This time he was sure that something alive was there besides himself, and he began to search.

The house was a good-sized one, and he examined every corner, but in vain. Then he raised his lantern and looked behind a tier of shelves which stood out a little way from the wall.

A dark figure was there crouching down. It was George Bentham, who, with a face white as ashes, came forth at Mr Naylor's command.
