"Who are you?" she asked at length. "You have not told me your real business."
"No, madam, and I ask your pardon. I feared that my real business, if suddenly made known to you, might startle, perhaps frighten you. I am a detective on the look-out for evidence in the case I have just mentioned. I have a theory that a most important witness in the same, drove by here at the hour and on the night I have named. I want to substantiate that theory. Can you help me?"
A sensitiveness to, and quick appreciation of, the character of those he addressed was one of Sweetwater's most valuable attributes. No glossing of the truth, however skillfully applied, would have served him with this woman so well as this simple statement, followed by its equally simple and direct inquiry. Scrutinising him over the child's head, she gave but a casual glance at the badge he took pains to show her, then in as quiet and simple tones as he had himself used, she made this reply:
"I can help you some. You make it my duty, and I have never shrunk from duty. A horse and cutter did go by here on its way uphill, last Tuesday night at about eleven o'clock. I remember the hour because I was expecting my husband every minute, just as I am now. He had some extra work on hand that night which he expected to detain him till eleven or a quarter after. Supper was to be ready at a quarter after. To surprise him I had beaten up some biscuits, and I had just put them in the pan when I heard the clock strike the hour. Afraid that he would come before they were baked, I thrust the pan into the oven and ran to the front door to look out. It was snowing very hard, and the road looked white and empty, but as I stood there a horse and cutter came in sight, which, as it reached the gate, drew up in a great hurry, as if something was the matter. Frightened, because I'm always thinking of harm to my husband whose work is very dangerous, I ran out bare-headed to the gate, when I saw why the man in the sleigh was making me such wild gestures. His hat had blown off, and was lying close up against the fence in front of me. Anxious always to oblige, I made haste to snatch at it and carry it out to its owner. I received a sort of thank you, and would never have remembered the occurrence if it had not been for that murder and if—" She paused doubtfully, ran her fingers nervously over her child's head, looked again at Sweetwater waiting expectantly for her next word, and faltered painfully—"if I had not recognised the horse."
Sweetwater drew a deep breath; it was such a happy climax. Then, as she showed no signs of saying more, asked as quietly as his rapidly beating heart permitted:
"Didn't you recognise the man?"
Her answer was short but as candid as her expression.
"No. The snow was blinding; besides he wore a high collar, in which his head was sunk down almost out of sight."
"But the horse—"
"Was one which is often driven by here. I had rather not tell you whose it is. I have not told any one, not even my husband, about seeing it on the road that night. I couldn't somehow. But if it will save a man's life and make clear who killed that good woman, ask any one on the Hill, in what stable you can find a grey horse with a large black spot on his left shoulder, and you will know as much about it as I do. Isn't that enough, sir? Now, I must dish up my dinner."
"Yes, yes; it's almost enough. Just one question, madam. Was the hat what folks call a derby? Like this one, madam," he explained, drawing his own from behind his back.
"Yes, I think so. As well as I can remember, it was like that. I'm afraid I didn't do it any good by my handling. I had to clutch it quick and I'm sure I bent the brim, to say nothing of smearing it with flour-marks."
"How?" Sweetwater had started for the door, but stopped, all eagerness at this last remark.
"I had been cutting out biscuits, and my hands were white with flour," she explained, simply. "But that brushes off easily; I don't suppose it mattered."
"No, no," he hastily assented. Then while he smiled and waved his hand to the little urchin who had been his means of introduction to this possibly invaluable witness, he made one final plea and that was for her name.
"Eliza Simmons," was the straightforward reply; and this ended the interview.
The husband, whose anticipated approach had occasioned all this abruptness, was coming down the hill when Sweetwater left the gate. As this detective of ours was as careful in his finish as in all the rest of his work, he called out as he went by:
"I've just been trying to sell a wonderful contrivance of mine to the missus. But it was no go."
The man looked, smiled, and went in at his own gate with the air of one happy in wife, child, and home.
Sweetwater went on up the hill. Towards the top, he came upon a livery-stable. Stopping in his good-humoured way, he entered into talk with a man loitering inside the great door. Before he left him, he had asked him these questions:
"Any grey horse in town?"
"Yes, one."
"I think I've seen it—has a patch of black on its left shoulder."
"Yes."
"Whose is it? I've a mighty curiosity about the horse. Looks like a trick horse."
"I don't know what you mean by that. It belongs to a respectable family. A family you must have heard about if you ever heard anything. There's a funeral there to-day—"
"Not Miss Cumberland's?" exclaimed Sweetwater, all agog in a moment.
"Yes, Miss Cumberland's. I thought you might have heard the name."
"Yes, I've heard it."
The tone was dry, the words abrupt, but the detective's heart was dancing like a feather. The next turn he took was toward the handsome residence district crowning the hill.
XI
IN THE COACH HOUSE
Fifteen minutes later, he stood in a finely wooded street before an open gateway guarded by a policeman. Showing his badge, he passed in, and entered a long and slightly curved driveway. As he did so, he took a glance at the house. It was not as pretentious as he expected, but infinitely more inviting. Low and rambling, covered with vines, and nestling amid shrubbery which even in winter gave it a habitable air, it looked as much the abode of comfort as of luxury, and gave—in outward appearance at least—no hint of the dark shadow which had so lately fallen across it.
The ceremonies had been set for three o'clock, and it was now half past two. As Sweetwater reached the head of the driveway, he saw the first of a long file of carriages approaching up the street.
"Lucky that my business takes me to the stable," thought he. "What is the coachman's name? I ought to remember it. Ah—Zadok! Zadok Brown. There's a combination for you!"
He had reached this point in his soliloquy (a bad habit of his, for it sometimes took audible expression) when he ran against another policeman set to guard the side door. A moment's parley, and he left this man behind; but not before he had noted this door and the wide and hospitable verandah which separated it from the driveway.
"I am willing to go all odds that I shall find that verandah the most interesting part of the house," he remarked, in quiet conviction, to himself, as he noted its nearness to the stable and the ease with which one could step from it into a vehicle passing down the driveway.
It had another point of interest, or, rather the wing had to which it was attached. As his eye travelled back across this wing, in his lively walk towards the stable, he caught a passing glimpse of a nurse's face and figure in one of its upper windows. This located the sick chamber, and unconsciously he hushed his step and moved with the greatest caution, though he knew that this sickness was not one of the nerves, and that the loudest sound would fail to reach ears lapsed in a blessed, if alarming, unconsciousness.
