'Smugglers!' declared Marjorie.
'Looks like it,' said Allan, as Hamish struck fresh matches and the others crowded round, giving utterance to ohs! and ahs! of excitement.
'They're at their old trade again,' said Allan, examining the barrels; 'I wonder what Pater will say to this?'
'That's the last match, Allan,' said Hamish, as the light flickered out.
The darkness seemed to come down like a weight, and the young people found themselves groping for each other's hands.
'We had better make the best of our way out of this,' said Allan. 'Try to move quietly, for we don't know who might be about. Help Tricksy, Hamish; I think she's by you, and here, Tricksy, give me your other hand.'
They groped their way towards the entrance, and soon were in the strong sunshine at the mouth of the caves.
'Well,' said Allan, 'that was an adventure;' and they looked at one another with varying expressions.
'Do you think they may have had anything to do with the robbery?' said Marjorie.
'Shouldn't wonder,' replied Allan. 'Anyhow, we'll see what Pater says.'
