"Mr. Garnesk gave me instructions, sir, which I read to the boatman who brought me here. Mr. Garnesk said I would find several fishermen at Mallaig who had motor-boats, and would bring me across. He also gave me this paper, and told me on no account to deviate from the directions he gave." Dennis held out his hand for the paper. He glanced through it, and then read it to Myra. "Take a motor-boat from Mallaig to Invermalluch Lodge," he read. "Tell the man to cross the top of Loch Hourn as if he were going to Glenelg, but when he gets well round the point he is to double back, and land you as near as he can to the house, but to keep on the far side of the point. You are on no account to be taken to the landing-stage at the lodge. When you arrive at the lodge insist on seeing Mr. Ewart, or Miss McLeod personally, if Mr. Ewart is not there. Then rejoin your motor-boat, and go on to Glenelg. Wait there for the first boat that will take you to Mallaig, and come back by the train. Do not return to Mallaig by motor-boat." "Those are very elaborate instructions, Mr. Burnham," said Myra. "It would seem that Mr. Garnesk is very suspicious about something." "Evidently," Dennis agreed. "You'd better let Miss McLeod have that parcel," he added to McKenzie. The youth handed him the parcel, and at Myra's suggestion Dennis opened it. Topmost among its contents was a letter addressed to me. Dennis tore it open and read it. "Miss McLeod is to wear a pair of these glasses until I see her again. She will be able to see through them fairly well, but she must not remove them. The consequences might be fatal. The three other pairs are for you and Burnham, and one extra in case of accidents. It will also come in handy if you take Hilderman into your confidence. Wear these glasses when you are in any danger of coming in contact with the green ray. I have an idea that they will act as a decided protection. I also enclose one Colt automatic pistol and cartridges, the only one I could get in the middle of the night. If you decide to ask Hilderman's help tell him everything. I am sure he will be very useful to you. Keep your courage up, old man! The best to you all. In haste.--H.G." "We're certainly learning something," said Dennis, as he finished. "Obviously Garnesk is very suspicious of somebody, but it's not Hilderman. He writes as if he were pretty sure of himself. Probably he has proved his theory about Hilderman being a Government detective." "I have a message for Mr. Ewart, sir," the messenger interrupted. "You had better tell it me," Dennis suggested. "I'd rather Miss McLeod asked me," McKenzie demurred. "Those were Mr. Garnesk's instructions. He said 'failing Mr. Ewart, insist on seeing Miss McLeod.'" "Very well," laughed Myra. "I quite appreciate your point. May I know the message?"
