'Hullo, good people!' cried a soft little voice from overhead, followed by a triumphant laugh.

Every one looked round, and half-way up the mast Tricksy was discovered, who having become annoyed at her desertion by Lieutenant Jones, was indulging in an exploring expedition on her own account.

Her little round face smiled mischievously from between a large white hat and tumbled frock, and she sat swinging her heels in perfect contentment.

Jim Macdonnell's duties having brought him to the quarter-deck at this moment, the captain made him a sign almost without pausing in the sentence which he was addressing to Mrs. Stewart.

The sailor climbed into the rigging and removed Tricksy very gently from her perch, tucked her under one arm with her head hanging in front and her heels behind, slid down the ropes and deposited the little girl on the deck.

Tricksy stood and looked at every one in speechless wrath. Her dignity, being as great as her anger, prevented her from giving way to an outburst before she should have discovered who deserved it most.

Lieutenant Jones crossed over to her.

'I suppose you have been round all this place before, Miss Tricksy,' he said in a conversational tone.

Tricksy looked at him with mistrust.

'I believe you are great explorers and rock-climbers, you and your brothers, Miss Tricksy,' continued the officer, as though being carried down from a mast before a crowd of people were a matter of everyday occurrence; 'I envy you your opportunities----'

This sounded quite like the way the other officers had been talking to the grown-up ladies, and Tricksy found her stiffness begin to forsake her.

The most important point was to discover whether the Sheriff had seen what had occurred. If he had not been a witness, Tricksy felt that she might allow herself to get over it.

Her eyes sought her enemy, but that magistrate was, or affected to be, engrossed in trying to bring his telescope to bear upon the caves, and the episode had apparently escaped him.

'Talking of people hiding in the caves,' he said suddenly; 'Mrs.

MacGregor, do you see the figure of a man at the mouth of the one which we are now opposite? From his att.i.tude he might be a fugitive from justice or any other of these interesting desperadoes about whom we have been talking----'

Marjorie's face flushed, and she began to tremble from head to foot.

'Wait a minute, Mrs. MacGregor,' said the Sheriff, 'I will get my gla.s.ses adjusted. Curious; there is something in the man's appearance which seems familiar to me----'

He was about to take another look when the air was rent by the shrill whistle of a siren.

They all turned round in astonishment, and when they looked towards the rocks again the figure had disappeared.

The captain's face had become stern, but the culprit proved to be only a small boy in a jacket whose sleeves were too short for him.

Marjorie had seen more, however; she had seen that it was Jim Macdonnell who had made Reggie blow the siren.

During the rest of the afternoon things seemed to be swimming before Marjorie's eyes, and she heard only a confused murmur of voices.

When the voyage was over she went straight to Allan.

'Allan,' she said abruptly, 'I may as well tell you that I know your secret. Neil is in Inchkerra--and he is in hiding.'

CHAPTER IX

DISAPPOINTMENT

Allan looked at Marjorie with his hands in his pockets.

'It's all right,' said Marjorie hastily; 'I won't tell any one, but I couldn't help finding it out, for I saw Neil. Anyhow, I know so much already that I might as well know the rest. To begin with, it was Neil's knife that you picked up in the Den; I saw the letters on the handle.'

Allan watched Marjorie narrowly for a minute, and then he seemed to become rea.s.sured.

'Listen, Marjorie,' he said; 'mind you don't let out a word of this to any one. It would be an awful thing if Neil were taken now. He came back a few days ago, in a smuggling vessel, to see his mother. Mrs.

Macdonnell is very ill, as you know'--Marjorie nodded, a lump being in her throat--'and she thinks she can't live long. Some one who knew where Neil was wrote and told him that she was always saying how much she wished she could see him before she died, and he came back at once, although the police may get him at any minute and he knows it. In the meanwhile she is much worse, and he refuses to go away until he sees whether she is going to recover. Mrs. Macdonnell keeps asking him to clear out, but he always says there is no hurry, and that he will wait until she is better. It's awfully senseless of him, for he might be seen any day; but Neil always was a bit obstinate once he takes a thing into his head. He hides most of the day and comes out when there isn't much chance of his meeting any one. But if he were found out he would be taken and sent to prison as sure as fate, so you must tell no one, Marjorie, not a soul. Reggie knows, but none of the others.'

Every particle of colour had left Marjorie's face, but her lips set themselves firmly.

'You needn't be afraid of me, Allan,' she said. 'We must get him persuaded to go away at once, for his mother would never get over it if he were caught.'

'Can't do anything just now,' said Allan; 'there is no way of getting him out of the island while the _Heroic_ is here, and this afternoon the men were declaring that as soon as they got sh.o.r.e leave they would search the island for the man who they say is "skulking round." We can only hope that they won't go very far into the caves, or that the ship will soon be ordered north. But, Marjorie, don't go about with a face like that, whatever you do, or you'll show people that something's the matter. Remember that if either the Pater or your father were to find out that Neil is here, it would be their duty to let the police know, and they wouldn't like to have to do that.'

Marjorie drew herself together.

'You needn't be afraid of me, Allan,' she said, as she turned away. 'I can keep a secret as well as you and Reggie, and you know it.'

On the following morning Allan was hardly surprised to encounter Marjorie upon the little hill which commanded a view of the sea near Ardnavoir. Her pony was beside her, and she had evidently risen with the dawn and ridden over the moors.

'Any news?' she inquired anxiously.

'Nothing at all,' he replied. 'The _Heroic_ is quite quiet yet, as you see.'

They looked at the dark hull which was lying motionless upon the water.

'Duncan rode over to the caves last night to tell Neil to keep out of sight while the _Heroic_ is here,' said Allan. 'The only fear is if the men should try exploring with torches. There are openings from the caves on to the moors, but if the island is swarming with men it wouldn't be much good trying to escape by them.'

'Oh,' cried Marjorie, looking at the _Heroic_, 'if only they would go away. Couldn't we invent some excuse for getting them out of the way while we get Neil into safety.'

'No good, I'm afraid,' said Allan. 'They have their orders from the Admiralty, and they wouldn't attend to anything else.'

Marjorie looked hopeless.

'I shall have to go home now,' she said; 'there's some one moving about in your garden, so it must be nearly breakfast-time. Let me know if there's any news.'

'Don't go yet,' said Allan decidedly. 'You must stay and have breakfast with us. I bet you didn't have anything before you left?'

'I had a crust of bread,' said Marjorie reluctantly. 'Elspeth keeps everything locked up at night, and I couldn't wait.'

'Come along,' said Allan. 'You'll be in the best place for seeing what the _Heroic_ is about.'

The argument was irresistible and Marjorie yielded.

'Never mind Cheeky,' said Allan; 'he won't wander far.'
