The farm hands—two smiling, middle-aged, and heavily moustached Italians, and a soft-eyed Mexican youth—I found in one of the fields. I talked to them for nearly two hours, and I left with a reasonable amount of assurance that none of the three had had any part in the shooting.
Dr. Rench had just come down from a visit to his patient when Gallaway and I returned from the fields. He was a little, wizened old man with mild manners and eyes, and a wonderful growth of hair on head, brows, cheeks, lips, chin, and nostrils.
The excitement, he said, had retarded Exon's recovery somewhat, but he did not think the setback would be serious. The invalid's temperature had gone up a little, but he seemed to be improving now.
I followed Dr. Rench out to his car after he left the others, for a few questions I wanted to put to him in privacy, but the questions might as well have gone unasked for all the good they did me. He could tell me nothing of any value. The nurse, Barbra Caywood, had been secured, he said, from San Francisco, through the usual channels, which made it seem unlikely that she had worked her way into the Exon house for any hidden purpose which might have some connection with the attempt upon Exon's life.
Returning from my talk with the doctor, I came upon Hilary Gallaway and the nurse in the hall, near the foot of the stairs. His arm was resting lightly across her shoulders, and he was smiling down at her. Just as I came through the door, she twisted away so that his arm slid off, laughed elfishly up into his face, and went on up the stairs.
I did not know whether she had seen me approaching before she eluded the encircling arm or not, nor did I know how long the arm had been there; and both of those questions would make a difference in how their positions were to be construed.
Hilary Gallaway was certainly not a man to allow a girl as pretty as the nurse to lack attention, and he was just as certainly attractive enough in himself to make his advances not too unflattering. Nor did Barbra Caywood impress me as being a girl who would dislike his admiration. But, at that, it was more than likely that there was nothing very serious between them, nothing more than a playful sort of flirtation.
But, no matter what the situation might be in that quarter, it didn't have any direct bearing upon the shooting—none that I could see, anyway. But I understood now the strained relations between the nurse and Gallaway's wife.
Gallaway was grinning quizzically at me while I was chasing these thoughts around in my head.
"Nobody's safe with a detective around," he complained.
I grinned back at him. That was the only sort of answer you could give this bird.
After dinner, Gallaway drove me to Knownburg in his roadster, and set me down on the doorstep of the deputy sheriff's house. He offered to drive me back to the Exon house when I had finished my investigations in town, but I did not know how long those investigations would take, so I told him I would hire a car when I was ready to return.
Shand, the deputy sheriff, was a big, slow-spoken, slow-thinking, blond man of thirty or so—just the type best fitted for a deputy sheriff job in a San Joaquin County town.
"I went out to Exon's as soon as Gallaway called me up," he said. "About four-thirty in the morning, I reckon it was when I got there. I didn't find nothing. There weren't no marks on the porch roof, but that don't mean nothing. I tried climbing up and down it myself, and I didn't leave no marks neither. The ground around the house is too firm for footprints to be followed. I found a few, but they didn't lead nowhere; and everybody had run all over the place before I got there, so I couldn't tell who they belonged to.
"Far's I can learn, there ain't been no suspicious characters in the neighbourhood lately. The only folks around here who have got any grudge against the old man are the Deemses— Exon beat 'em in a law suit a couple years back—but all of them—the father and both the boys—were at home when the shooting was done."
"How long has Exon been living here?"
"Four-five years, I reckon."
"Nothing at all to work on, then?"
"Nothing I know about."
"What do you know about the Exon Family?" I asked.
Shand scratched his head thoughtfully and frowned.
"I reckon it's Hilary Gallaway you're meaning," he said slowly. "I thought of that. The Gallaways showed up here a couple of years after her father had bought the place, and Hilary seems to spend most of his evenings up in Ady's back room, teaching the boys how to play poker. I hear he's fitted to teach them a lot. I don't know, myself. Ady runs a quiet game, so I let 'em alone. But naturally I don't never set in, myself.
"Outside of being a cardhound, and drinking pretty heavy, and making a lot of trips to the city, where he's supposed to have a girl on the string, I don't know nothing much about Hilary. But it's no secret that him and the old man don't hit it off together very well. And then Hilary's room is just across the hall from Exon's, and their windows open out on the porch roof just a little apart. But I don't know—"
Shand confirmed what Gallaway had told me about the bullet being .38 calibre, about the absence of any pistol of that calibre on the premises, and about the lack of any reason for suspecting the farm hands or servants.
I put in the next couple of hours talking to whomever I could find to talk to in Knownbure, and I learned nothing worth putting down on paper. Then I got a car and driver from the garage, and was driven out to Exon's.
Gallaway had not yet returned from town. His wife and Barbra Caywood were just about to sit down to a light dinner before retiring, so I joined them. Exon, the nurse said, was asleep, and had spent a quiet evening. We talked for a while—until about half-past twelve —and then went to our rooms.
My room was next to the nurse's, on the same side of the hall that divided the second story in half. I sat down and wrote my report for the day, smoked a cigar, and then, the house being quiet by this time, put a gun and a flashlight in my pockets, went downstairs, and out the kitchen door.
The moon was just coming up, lighting the grounds vaguely, except for the shadows cast by house, outbuildings, and the several clumps of shrubbery. Keeping in these shadows as much as possible, I explored the grounds, finding everything as it should be.
The lack of any evidence to the contrary pointed to last night's shot having been fired— either accidentally, or in fright at some fancied move of Exon's—by a burglar, who had been entering the sick man's room through a window. If that were so, then there wasn't one chance in a thousand of anything happening to-night. But I felt restless and ill at ease, nevertheless.
Gallaway's roadster was not in the garage. He had not returned from Knownburg. Beneath the farm hands' window I paused until snores in three distinct keys told me that they were all safely abed.
After an hour of this snooping around, I returned to the house. The luminous dial of my watch registered 2:35 as I stopped outside the Chinese cook's door to listen to his regular breathing.
Upstairs, I paused at the door of the Figgs's room, until my ear told me that they were sleeping. At Mrs. Gallaway's door I had to wait several minutes before she sighed and turned in bed. Barbra Caywood was breathing deeply and strongly, with the regularity of a young animal whose sleep is without disturbing dreams. The invalid's breath came to me with the evenness of slumber and the rasping of the pneumonia convalescent.
This listening tour completed, I returned to my room.
Still feeling wide-awake and restless, I pulled a chair up to a window, and sat looking at the moonlight on the river which twisted just below the house so as to be visible from this side, smoking another cigar, and turning things over in my mind—to no great advantage.
