h, indeed," said Dennis, his suspicions aroused at once. Garnesk, he
knew, had only arrived in Glasgow the night before.

"I see you are wondering how I got here and why I came down the hill,
instead of up a road of some sort," said the youth with a smile.

"Frankly, I was," Dennis admitted.

"Then, perhaps, I had better explain who I am and how I come to
be here. My name is McKenzie. I am employed by Welton and Delaunay,
the Glasgow opticians, makers of the 'Weldel' telescopes and
binoculars. Mr. Garnesk has a good deal to do with our firm in the
matter of designs for special glasses to withstand furnace heat, for
ironworkers, etc. He arrived at the works last night in a car, and,
after consulting with the manager, they kept a lot of us at work all
night on a new design of spectacles.

"I was sent with this parcel in the early hours of the morning.
There was no passenger train, but Mr. Garnesk got me a military pass
on a fish train, and here I am. I was to deliver the parcel to Mr.
Ewart, or, failing him, to Miss McLeod. When I saw this lady with
the--er--the shade over her eyes I thought you were probably Mr.
Ewart, sir."

"I'm not, as a matter of fact," said Dennis. "But where have you come
from, and why didn't you come up the path?"

"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 agre
