No one knew anything about the door, and, in spite of his anger, Peet was obliged to admit he himself must have left it open, since none of the under-gardeners could have got possession of the key. As far as he knew, they had no interest in going in. The ruin was only used by him for a secret purpose of his own of which he had spoken to no one. On one occasion alone had he ever allowed any of his underlings into it. That was on the day he had made Thomas assist him in erecting some woodwork in preparation for a gift he had received from his brother in India, which he desired to keep a profound secret from everybody. Inside the ruin was a recess large enough for his purpose; but it required a good deal of adapting to make it available, and this he could not manage without help. Thomas's action in throwing the piece of wood might or might not be regarded as suspicious, but since he had been out boating with the children, he could not have had anything to do with opening the door. He might desire to get in if his curiosity about the woodwork in the recess had been roused, but was that likely in such a stupid lout as Thomas?

There really appeared to be no one on whom he could visit his wrath. Dismissing the under-gardeners curtly, he was forced to return to his work in a very unenviable frame of mind, suspicious of everybody.

Meantime the children were greatly taken aback by the quarrel between Alan and Peet. The two were always more or less at daggers drawn, but it was seldom that the mutual dislike blazed up into open war.

'I will show Peet a thing or two,' cried Alan with a wilful smile. 'He must learn he can't speak to me like that. He is Aunt Betty's servant, worse luck. If he had been Father's, I'd have been down on him with a vengeance.'

'It is a great pity to quarrel with him,' said Marjorie, though she knew the remark was not a wise one under the circumstances. 'He is an old man, he's seen heaps of trouble, and he's soured. That is what Aunt Betty says. I think it would be nicer—- more like what one would call noblesse oblige—if we let him alone.'

'There's Father!' cried Georgie with a shout. 'We can ask him.'
