(Tuesday, June 18; 9 a.m.)

The next day—the fourth of the investigation—was an important and, in some ways, a momentous one in the solution of the problem posed by Alvin Benson’s murder. Nothing of a definite nature came to light, but a new element was injected into the case; and this new element eventually led to the guilty person.

Before we parted from Markham after our dinner with Major Benson, Vance had made the request that he be permitted to call at the District Attorney’s office the next morning. Markham, both disconcerted and impressed by his unwonted earnestness, had complied; although, I think, he would rather have made his arrangements for Captain Leacock’s arrest without the disturbing influence of the other’s protesting presence. It was evident that, after Higginbotham’s report, Markham had decided to place the Captain in custody, and to proceed with his preparation of data for the Grand Jury.

Although Vance and I arrived at the office at nine o’clock Markham was already there. As we entered the room, he picked up the telephone receiver, and asked to be put through to Sergeant Heath.

At that moment Vance did an amazing thing. He walked swiftly to the District Attorney’s desk and, snatching the receiver out of Markham’s hand, clamped it down on the hook. Then he placed the telephone to one side, and laid both hands on the other’s shoulders. Markham was too astonished and bewildered to protest; and before he could recover himself, Vance said in a low, firm voice, which was all the more impelling because of its softness:

“I’m not going to let you jail Leacock,—that’s what I came here for this morning. You’re not going to order his arrest as long as I’m in this office and can prevent it by any means whatever. There’s only one way you can accomplish this act of unmitigated folly, and that’s by summoning your policemen and having me forcibly ejected. And I advise you to call a goodly number of ’em, because I’ll give ’em the battle of their bellicose lives!”

The incredible part of this threat was that Vance meant it literally. And Markham knew he meant it.

“If you do call your henchmen,” he went on, “you’ll be the laughing stock of the city inside of a week; for, by that time, it’ll be known who really did shoot Benson. And I’ll be a popular hero and a martyr—God save the mark!—for defying the District Attorney and offering up my sweet freedom on the altar of truth and justice and that sort of thing. . . .”

The telephone rang, and Vance answered it.

“Not wanted,” he said, closing off immediately. Then he stepped back and folded his arms.
