The only other incident was that Donald Macdonald and the new gillie, Duncan Mackay, were reported to be 'lying around in a frightfully dissolute state.' Donald was a sober man, but Mackay, he explained next morning, proved to be his long lost cousin, hence the revel. Mackay, separately, stated that he had made Donald intoxicated for the purpose of eliciting any guilty secret which he might possess. But whisky had elicited nothing. On the whole the London detectives had not been entirely a success. Mr. Macrae therefore arranged to send both of them back to Lairg, where they would strike the line, and return to the metropolis. Merton had casually talked of Logan (Lord Fastcastle) to Mr. Macrae on the previous evening, and mentioned that he was now likely to be at Inchnadampf. Mr. Macrae knew something of Logan, and before he sped the parting detectives, asked Merton whether he thought that he might send a note to Inchnadampf inviting his friend to come and bear him company? Merton gravely said that in such a crisis as theirs he thought that Logan would be extremely helpful, and that he was a friend of the Budes. Perhaps he himself had better go and pick up Logan and inform him fully as to the mysterious events? As Mr. Gianesi was also expected from London on that day (Thursday) to examine the wireless machine, which had been silent, Mr. Macrae sent off several vehicles, as well as the motor that carried the detectives. Merton drove the tandem himself. Merton found Logan, with his Spanish bull-dog, Bouncer, loafing outside the hotel door at Inchnadampf. He greeted Merton in a state of suppressed glee; the whole adventure was much to the taste of the scion of Rostalrig. Merton handed him Mr. Macrae's letter of invitation. 'Come, won't I come, rather!' said Logan. 'Of course we must wait to rest the horses,' said Merton. 'The motor has gone on to Lairg, carrying two detectives who have made a pretty foozle of it, and it will bring back an electrician.' 'What for?' asked Logan. 'I must tell you the whole story,' said Merton. 'Let us walk a little way--too many gillies and people loafing about here.' They walked up the road and sat down by little Loch Awe, the lochan on the way to Alt-na-gealgach. Merton told all the tale, beginning with his curious experiences on the night before the disappearance of Miss Macrae, and ending with the dismissal of the detectives. He also confided to Logan the importance of the matter to himself, and entreated him to be serious. Logan listened very attentively. When Merton had ended, Logan said, 'Old boy, you were the making of me: you may trust me. Serious it is. A great deal of capital must have been put into this business.' 'A sprat to catch a whale,' said Merton. 'You mean about nobbling the electric machine? How could _that_ be done?' 'That--and other things. I don't know _how_ the machine was nobbled, but it could not be done cheap. Would you mind telling me your dreams again?'
