"Seventy-seven!"

"Je suis la!" came her voice from the stairs.

"It's all right," he said, "it's one of our men. No use sittin' up if you're sleepy." He listened but did not hear Miss Erith stir.

"Better return to bed," he said again, and guided Sixty-seven into the room on the left.

For a few moments he prowled around; a gla.s.s tinkled against a decanter. When he returned to the shadow-shape seated motionless by the cas.e.m.e.nt window he carried only one gla.s.s.

"Don't you?" inquired Sixty-seven. "And you a Scot!"

"I'm a Yankee; and I'm through."

"With the stuff?"

"Absolutely."

"Oh, very well. But a Yankee laird--tiens c'est a.s.sez drole!" He smacked his lips over the smoky draught, set the half-empty gla.s.s on the deep sill. Then he began breezily:

"Well, Seventy-six, what's all this I hear about your misfortunes?"

"What do you hear?" inquired McKay guilelessly.

The other man laughed.

"I hear that you and Seventy-seven have entered the Service; that you are detailed to Switzerland and for a certain object unknown to myself; that your transport was torpedoed a week ago off the Head of Strathlone, that you wired London from this house of yours called Isla, and that you and Seventy-seven went to London last week to replenish the wardrobe you had lost."

"Is that all you heard?"

"It is."

"Well, what more do you wish to hear?"

"I want to know whether anything has happened to worry you. And I'll tell you why. There was a Hun caught near Banff! Can you beat it?

The beggar wore kilts!--and the McKay tartan--and, by jinks, if his gillie wasn't rigged in shepherd's plaid!--and him with his Yankee pa.s.sport and his gillie with a bag of ready-made rods. Yellow trout, is it? Sea-trout, is it! Ho, me bucko, says I when I lamped what he did with his first trout o' the burn this side the park--by G.o.dfrey!

thinks I to myself, you're no white man at all!--you're Boche. And it was so, McKay."

"Seventy-six," corrected McKay gently.

"That's better. It should become a habit."

"Excuse me, Seventy-six; I'm Scotch-Irish way back. You're straight Scotch--somewhere back. We Yankees don't use rods and flies and net and gaff as these Scotch people use 'em. But we're white, Seventy-six, and we use 'em RIGHT in our own fashion." He moistened his throat, shoved aside the gla.s.s:

"But this kilted Boche! Oh, la-la! What he did with his rod and flies and his fish and himself! AND his gillie! Sure YOU'RE not white at all, thinks I. And at that I go after them."

"You got them?"

"Certainly--at the inn--gobbling a trout, blaue gesotten--having gone into the kitchen to show a decent Scotch la.s.sie how to concoct the Hunnish dish. I nailed them then and there--took the chance that the swine weren't right. And won out."

"Good! But what has it to do with me?" asked McKay.

"Well, I'll be telling you. I took the Boche to London and I've come all the way back to tell you this, Seventy-six; the Huns are on to you and what you're up to. That Boche laird called himself Stanley Brown, but his name is--or was--Schwartz. His gillie proved to be a Swede."

"Have they been executed?"

"You bet. Tower style! We got another chum of theirs, too, who set up a holler like he saw a pan of hogwash. We're holding him. And what we've learned is this: The Huns made a special set at your transport in order to get YOU and Seventy-seven!

"Now they know you are here and their orders are to get you before you reach France. The hog that hollered put us next. He's a Milwaukee Boche; name Zimmerman. He's so scared that he tells all he knows and a lot that he doesn't. That's the trouble with a Milwaukee Boche. Anyway, London sent me back to find you and warn you. Keep your eye skinned. And when you're ready for France wire Edinburgh.

You know where. There'll be a car and an escort for you and Seventy-seven."

McKay laughed: "You know," he said, "there's no chance of trouble here. Glenark is too small a village--"

"Didn't I land a brace of Boches at Banff?"

"That's true. Well, anyway, I'll be off, I expect, in a day or so."

He rose; "and now I'll show you a bed--"

"No; I've a dog-cart tied out yonder and a chaser lying at Glenark.

By G.o.dfrey, I'm not finished with these Boche-jocks yet!"

"You're going?"

"You bet. I've a date to keep with a suspicious character--on a trawler. Can you beat it? These vermin creep in everywhere. Yes, by G.o.dfrey! They crawl aboard ship in sight of Strathlone Head! Here's hoping it may be a yard-arm jig he'll dance!"

He emptied his gla.s.s, refused more. McKay took him to the wicket and let him loose.

"Well, over the top, old scout!" said Sixty-seven cheerily, exchanging a quick handclasp with McKay. And so the fog took him.

A week later they found his dead horse and wrecked dog-cart five miles this side of Glenark Burn, lying in a gully entirely concealed by whinn and broom. It was the noise the flies made that attracted attention. As for the man himself, he floated casually into the Firth one sunny day with five bullets in him and his throat cut very horridly.

But, before that, other things happened on Isla Water--long before anybody missed No. 67. Besides, the horse and dog-cart had been hired for a week; and n.o.body was anxious except the captain of the trawler, held under mysterious orders to await the coming of a man who never came.

So McKay went back through the fog to his quaint, whitewashed inheritance--this legacy from a Scotch grandfather to a Yankee grandson--and when he came into the dark waist of the house he called up very gently: "Are you awake, Miss Yellow-hair?"

"Yes. Is all well?"

"All's well," he said, mounting the stairs.

"Then--good night to you Kay of Isla!" she said.

"Don't you want to hear--"

"To-morrow, please."

"But--"

"As long as you say that all is well I refuse to lose any more sleep!"
