The detective instinct was alive in Louise. She hazarded a startling query:

"Who killed Captain Wegg?" she demanded, suddenly.

Another smile preceded the reply.

"A dreadful foe called heart disease. But come; let me show you my garden. There are no such roses as these for miles around."

Louise was confident she had made progress. Ethel had admitted several things that lent countenance to the suspicions already aroused; but perhaps this simple country girl had never imagined the tragedy that had been enacted at her very door.

She cordially urged Ethel Thompson to spend a day with them at the farm, and Uncle John, who was pleased with the modesty and frankness of the fair-haired little school teacher, earnestly seconded the invitation.

Then he thought of going home, and the thought reminded him of Dan.

"Do you know," he inquired, "where I could buy a decent horse?"

The girl looked thoughtful a moment; then glanced up with a bright smile.

"Will you buy one off me?" she asked.

"Willingly, my dear, if you've an animal to sell."

"It's--it's our Joe. He was grandfather's favorite colt when his trouble came upon him. We have no use for him now, for I always ride or drive my pony. And grandmother says he's eating his head off to no purpose; so we'd like to sell him. If you will come to the barn I'll introduce you to him."

Joe proved on inspection to be an excellent horse, if appearances were to be trusted, and Ethel a.s.sured Mr. Merrick that the steed was both gentle and intelligent.

"Do you use that surrey?" inquired Uncle John, pointing to a neat vehicle that seemed to be nearly new.

"Very seldom, sir. Grandmother would like to sell it with the horse."

"It's exactly what I need," declared Mr. Merrick. "How much for Joe and his harness, and the surrey?"

"I'll go and ask what grandmother wants."

She returned after a few minutes, stating a figure that made Uncle John lift his brows with a comical expression.

"A hundred dollars! Do you take me for a brigand, little girl? I know what horses are worth, for I've bought plenty of 'em. Your Joe seems sound as a dollar, and he's just in his prime. A hundred and fifty is dirt cheap for him, and the surrey will be worth at least seventy-five.

Put in the harness at twenty-five, and I'll give you two-fifty for the outfit, and not a cent more or less. Eh?"

"No, indeed," said Ethel. "We could not get more than a hundred dollars from anyone else around here."

"Because your neighbors are countrymen, and can't afford a proper investment. So when they buy at all they only give about half what a thing is actually worth. But I'll be honest with you. The price I offer is a good deal less than I'd have to pay in the city--Hutchinson would charge me five hundred, at least--and I need just what you've got to sell. What do you say, Miss Ethel?"

"The price is one hundred dollars, Mr. Merrick."

"I won't pay it. Let me talk with your grandmother."

"She does not see anyone, sir."

Louise looked up sharply, scenting another clue.

"Isn't she well, dear?" she asked in smooth tones.

"She looks after grandfather, and helps Aunt Lucy with the housework."

"Well, come, Louise; we'll go home," said Uncle John, sadly. "I'd hoped to be able to drive this fine fellow back, but Dan'll have to groan an'

balk all the way to the farm."

Ethel smiled.

"Better buy at my price, Mr. Merrick," she suggested.

"Tell you what I'll do," he said, pausing. "I'll split the difference.

Take two hundred and well call it a bargain."

"But I cannot do that, sir."

"It will help pay you for the hard work of fixing up the house," he rejoined, pleadingly. "Your bill wasn't half enough."

"My bill?" wonderingly.

"The one I paid Mc.n.u.tt for your services."

"I made no charge, sir. I could not accept anything for a bit of a.s.sistance to a neighbor."

"Oh! Then Mc.n.u.tt got it, did he?"

"I'm awfully sorry, Mr. Merrick. I told Peggy I would not accept payment."

"H-m. Never mind. We're not going to quarrel, little neighbor. May I hitch Joe to the surrey?"

"If you like. I'll help you."

Uncle John led Joe from his stall and together they harnessed the horse to the surrey. The girl knew better than the man how to buckle the straps properly, while Louise stood by helplessly and watched the performance.

Then Uncle John went for old Dan, whom he led, rickety buggy and all, into the Thompson stable.

"I'll send Hucks over to get him, although we might as well knock him in the head," he said as he unharnessed the ancient steed. "Now then, Louise, hop in."

"You'll be sure to come over Thursday, for the day, Miss Thompson?"

asked Louise, taking Joe's reins from her uncle's hands.

"I'll not forget such a delightful engagement, be sure."

Uncle John had his pocketbook out, and now he wadded up some bills and thrust them into the little school teacher's hand.

"Drive ahead, Louise," he called. "Good morning, my dear. See you on Thursday."

As the vehicle rolled out of the yard and turned into the highway, Ethel unrolled the bills with trembling fingers.
