Within the heart itself were three people—Ilam; a middle-aged man named Gloucester, who spent all his days in counting and weighing gold and silver, and who was the presiding genius of the heart; and, thirdly, a clerk from the London and West-End Bank.

Gloucester was weighing sovereigns, the clerk was counting coffers and piling them up in a corner near the door, and Ilam was idly inspecting the doors of the huge safe, which had been raised out of its well and stood open and empty.

During that day and the previous two days, what with a monster Y.M.C.A. fête then in progress, and what with the weather, over a million shillings had been taken at the turnstiles. Now, a new shilling weighs eighty-seven grains, and about seven thousand average current shillings go to the hundredweight. A million shillings, or fifty thousand pounds in silver, will weigh, therefore, something like seven tons. Nearly the whole of this treasure had already started on its way to the famous vaults of the London and West-End Bank; only a few coffers remained. But there was, in addition, about ten thousand pounds in gold, which weighed about a couple of hundredweight, and it was chiefly for this gold that the last automobile was waiting.

“Seven coffers of silver, Mr. Gloucester,” said the clerk; “two of gold.”

“I shall be ready with the others in a few minutes,” replied Mr. Gloucester.

“Then I’ll be making out the check-sheets,” said the clerk.

“Do so,” said Mr. Gloucester, who was a formal old person, and wore steel-rimmed spectacles. And he continued his weighing of the gold.

At this interesting and dazzling juncture, the unique door of the apartment, an affair of solid Bessemer steel, swung slowly on its hinges, and disclosed the figure of a man in a blue suit, with grey hair under his soft hat. Mr. Gloucester, being just a little short-sighted and just a little hard of hearing, neither saw nor heard the visitor. Nor did Mr. Ilam, who was actually within the safe, measuring its-shelves. But the bank-clerk, who was quite close to the door, most decidedly did see the man. And the clerk started, whether with fear, surprise, or mere nervousness, will probably never be known.

The man shut the door.

“What——” began the clerk.
