“It impresses me,” Tinkham said coldly, “as kindergarten stuff.”
“Ah, Colonel,” Wolfe wiggled a finger at him, “but it worked!” He wiggled the finger at the desk. “As General Fife remarked, he doesn’t see it now. It’s gone.”
They all goggled at him. Then, as the implication soaked in, they looked at one another. Currents of startled inquiry, uneasiness, distrust, darted from one pair of eyes to another, here and there, in all directions, crossing, meeting.
Fife barked at Wolfe, “What the hell are you talking about? What are you insinuating?”
“Nothing,” Wolfe said quietly. “I’m merely reporting. I know you gentlemen are on edge, but even so you might let me finish. As I said, Fritz entered to look things over after each of you had been in here ten minutes. And all of you passed the test admirably. Lawson, Tinkham, Fife, Shattuck. But there was another. The last to come was Miss Bruce. She too had her allotted ten minutes. But, gentlemen, she remained for only seven of them! The keyhole of the kitchen door commands a view of the hall. After seven minutes Fritz saw Miss Bruce emerge from the office and depart by the front door. He came in here — and both the envelope and the grenade were gone! Why she took the grenade I don’t know, unless for the purpose of hurling it through the window at me.”
They all glanced at the window, and I did too, to make it unanimous.
Fife was on his feet. “I want to use that phone.”
Wolfe shook his head. “It requires a little discussion, General. For one thing, we can’t afford to make enemies of the police. For another, they are already attending to Miss Bruce. I arranged with Inspector Cramer to post men outside, to follow any of you, including Miss Bruce, who left the house before one o’clock. For still another, General Carpenter phoned me from Washington last evening and gave me some special instructions. As I said, he sent me that grenade. And with it, the instructions in writing. So if you’ll bear with me a little longer—”
Fife sat down.
“I do not state,” Wolfe said, “that Miss Bruce murdered Colonel Ryder. She has the appearance of a resourceful and determined woman, but we certainly haven’t enough evidence to charge her with murder. Why she stayed in here seven minutes, instead of seizing the envelope as soon as she saw it and leaving with it, I don’t know. She may have been coolheaded enough to open it and examine the contents, but that doesn’t seem likely, since all it contained was blank sheets of paper. At any rate, we can now start to work on her, and whether her wrongdoing went to the length of murder or not, she’ll pay for whatever she did.” Wolfe frowned. “I admit I don’t like her having that grenade. I didn’t foresee that. If she gets in a corner and kills someone with it—” He shrugged. “Archie, you’d better phone Mr. Cramer and tell him to warn his men — but first, where’s that letter from General Carpenter? Have you got it in your desk?”
