"At what time was it you thought you heard this shot?"
"I dunno, to the minute."
"Was it before James Cunningham went up in the elevator? Was it between the time he went up an" the other two went up? Or was it after Jack Cunningham an" Miss Harriman pa.s.sed on the way up?"
"Seems to me it was--"
"Hold on." Kirby raised a hand in protest. "I don"t want any guesses.
You know or you don"t. Which is it?"
"I reckon it was between the time yore cousin James went up an" the others followed."
"You reckon? I"m askin" for definite information. A man"s life may hang on this." The cattleman"s eyes were ice-cold.
Hull swallowed a lump in his fat throat before he committed himself.
"Well, it was."
"Was between the two trips of the elevator, you mean?"
"Yes."
"Your wife heard this sound, too?"
"Yep. We spoke of it afterward."
"Do you know anything else that could possibly have had any bearing on my uncle"s death?"
"No, sir. Honest I don"t."
Olson shot a question at the man on the grill. "Did you kill the j.a.p servant, too, as well as his boss?"
"I didn"t kill either the one or the other, so help me."
"Do you know anything at all about the j.a.p"s death? Did you see anything suspicious going on at any time?" Kirby asked.
"No, sir. Nothin" a-tall."
The rough rider signaled the taxicab, which was circling the lake at the foot of the hill. Presently it came up the incline and took on its pa.s.sengers.
"Drive to the Paradox Apartments," Kirby directed.
He left Hull outside in the cab while he went in to interview his wife.
The lean woman with the forbidding countenance opened the door.
Metaphorically speaking, Kirby landed his knockout instantly. "I"ve come to see you on serious business, Mrs. Hull. Your husband has confessed how he did for my uncle. Unless you tell the whole truth he"s likely to go to the death cell."
She gasped, her fear-filled eyes fastened on him. Her hand moved blindly to the side of the door for support.
CHAPTER x.x.xVIII
A FULL MORNING
But only for an instant. A faint color dribbled back into her yellow cheeks. He could almost see courage flowing again into her veins.
"That"s a lie," she said flatly.
"I don"t expect you to take my word. Hull is in front of the house here under guard. Come an" see if you doubt it."
She took him promptly at his suggestion. One look at her husband"s fat, huddled figure and stricken face was enough.
"You chicken-hearted louse," she spat at him scornfully.
"They had evidence. A man saw us," he pleaded.
"What man?"
"This man." His trembling hand indicated Olson. "He was standin" on the fire escape acrost the alley."
She had nothing to say. The wind had died out of the sails of her anger.
"We"re not goin" to arrest Hull yet--not technically," Kirby explained to her. "I"m arrangin" to hire a private detective to be with him all the time. He"ll keep him in sight from mornin" till night. Is that satisfactory, Hull? Or do you prefer to be arrested?"
The wretched man murmured that he would leave it to Lane.
"Good. Then that"s the way it"ll be." Kirby turned to the woman.
"Mrs. Hull, I want to ask you a few questions. If you"ll kindly walk into the house, please."
She moved beside him. The shock of the surprise still palsied her will.
In the main her story corroborated that of Hull. She was not quite sure when she had heard the shot in its relation to the trips of the elevator up and down. The door was closed at the time. They had heard it while standing at the window. Her impression was that the sound had come after James Cunningham had ascended to the floor above.
Kirby put one question to the woman innocently that sent the color washing out of her cheeks.
"Which of you went back upstairs to untie my uncle after you had run away in a fright?"
"N-neither of us," she answered, teeth chattering from sheer funk.
"I understood Mr. Hull to say--"
"He never said that. Y-you must be mistaken."
"Mebbeso. You didn"t go back, then?"
The monosyllable "No" came quavering from her yellow throat.
"I don"t want you to feel that I"m here to take an advantage of you, Mrs. Hull," Kirby said. "A good many have been suspected of these murders. Your husband is one of these suspects. I"m another. I mean to find out who killed Cunningham an" Horikawa. I think I know already. In my judgment your husband didn"t do it. If he did, so much the worse for him. No innocent person has anything to fear from me.
