'That will be the best chance of getting him,' replied Allan.

'The fellow will find himself in the wrong box then, won't he, Neil?'

'I suppose he will,' replied Neil, rather absently.

'I hope it won't turn out to have been some one on the island,' said Reggie.

'I hope not,' said Marjorie, looking over to the green fields and brown heather moors of Inchkerra. 'Isn't it dreadful to think that it may have been some one whom we know; some one we have spoken to quite lately?'

'Well, Miss Marjorie,' said Neil, 'do you not think we had better be getting the table cleared and the things put away? We have plenty of work before us, if we are to plant all Reggie's ferns; and we must not stay too late, for it iss anxious about you that Mrs. Stewart and Mrs. MacGregor will be.'

'Not they,' said Tricksy; 'no one is anxious when they know that you are with us, Neil.'

Neil looked gratified, and the young people began to collect the dishes.

'Now, don't you bother about this piece of work,' said Marjorie, when the boys had carried the plates into the cottage; 'you go and amuse yourselves out-of-doors while Tricksy and I wash the dishes.'

'I wonder why you don't let them do their share of the disagreeable work, Marjorie,' said Tricksy a little discontentedly, when the boys had vanished.
