Spargo suddenly remembered his bit of bluff to Miss Baylis. Here was an unexpected result of it.

“Nobody but me can help you to trace Maitland’s boy,” continued Mother Gutch, “and I shall expect to be paid accordingly. That’s plain language, young man.”

Spargo considered the situation in silence for a minute or two. Could this wretched, bibulous old woman really be in possession of a secret which would lead to the solving of the mystery of the Middle Temple Murder? Well, it would be a fine thing for the Watchman if the clearing up of everything came through one of its men. And the Watchman was noted for being generous even to extravagance in laying out money on all sorts of objects: it had spent money like water on much less serious matters than this.

“How much do you want for your secret?” he suddenly asked, turning to his companion.

Mother Gutch began to smooth out a pleat in her gown. It was really wonderful to Spargo to find how very sober and normal this old harridan had become; he did not understand that her nerves had been all a-quiver and on edge when he first met her, and that a resort to her favourite form of alcohol in liberal quantity had calmed and quickened them; secretly he was regarding her with astonishment as the most extraordinary old person he had ever met, and he was almost afraid of her as he waited for her decision. At last Mother Gutch spoke.

“Well, young man,” she said, “having considered matters, and having a right to look well to myself, I think that what I should prefer to have would be one of those annuities. A nice, comfortable annuity, paid weekly—none of your monthlies or quarterlies, but regular and punctual, every Saturday morning. Or Monday morning, as was convenient to the parties concerned—but punctual and regular. I know a good many ladies in my sphere of life as enjoys annuities, and it’s a great comfort to have ’em paid weekly.”

It occurred to Spargo that Mrs. Gutch would probably get rid of her weekly dole on the day it was paid, whether that day happened to be Monday or Saturday, but that, after all, was no concern of his, so he came back to first principles.

“Even now you haven’t said how much,” he remarked.

“Three pound a week,” replied Mother Gutch. “And cheap, too!”

Spargo thought hard for two minutes. The secret might—might!—lead to something big. This wretched old woman would probably drink herself to death within a year or two. Anyhow, a few hundreds of pounds was nothing to the Watchman. He glanced at his watch. At that hour—for the next hour—the great man of the Watchman would be at the office. He jumped to his feet, suddenly resolved and alert.
