"Excellent! We can do that—very fine work, Doctor! Miss Morgan, get District at once!"

This, too, should have warned Kinnison, but it did not. He went back to the Laboratory.

Tempus fugited.

Orders came to get ready to load M67 H.E., A.T. (105 m/m High Explosive, Armor Tearing) shell on the Nine, and the Siberians went joyously to work upon the new load. The explosive was to be a mixture of TNT and a polysyllabic compound, everything about which was highly confidential and restricted.

"But what the hell's so hush-hush about that stuff?" demanded Blondie, who, with five or six others, was crowding around the Czar's desk. Unlike the days of Cappy Sumner, the private office of the Chief Chemist was now as much Siberia as Siberia itself. "The Germans developed it originally, didn't they?"

"Yes, and the Italians used it against the Ethiopians—which was why their bombs were so effective. But it says 'hush-hush,' so that's the way it will be. And if you talk in your sleep, Blondie, tell Betty not to listen."

The Siberians worked. The M67 was put into production. It was such a success that orders for it came in faster than they could be filled. Production was speeded up. Small cavitations began to appear. Nothing serious, since they passed Inspection. Nevertheless, Kinnison protested, in a formal report, receipt of which was formally acknowledged.

General Somebody-or-other, Entwhistle's Commanding Officer, whom none of the Siberians had ever met, was transferred to more active duty, and a colonel—Snodgrass or some such name—took his place. Ordnance got a new Chief Inspector.

An M67, Entwhistle loaded, prematured in a gun-barrel, killing twenty seven men. Kinnison protested again, verbally this time, at a staff meeting. He was assured—verbally—that a formal and thorough investigation was being made. Later he was informed—verbally and without witnesses—that the investigation had been completed and that the loading was not at fault. A new Commanding Officer—Lieutenant-Colonel Franklin—appeared.

The Siberians, too busy to do more than glance at newspapers, paid very little attention to a glider-crash in which several notables were killed. They heard that an investigation was being made, but even the Czar did not know until later that Washington had for once acted fast in correcting a bad situation; that Inspection, which had been under Production, was summarily divorced therefrom. And gossip spread abroad that Stillman, then Head of the Inspection Division, was not a big enough man for the job. Thus it was an entirely unsuspecting Kinnison who was called into the innermost private office of Thomas Keller, the Superintendent of Production.
