"You have a suspicious mind and an eye for detail," Winter said. "We maneuvered the scout through the streets to the position of the ramps before going into drive. We're on the north side of the city now."

Our giant car roared across a bridge, and swirled into a long gravel drive leading to a wrought-iron gate before a massive grey granite building. The people I saw looked perfectly ordinary, with the exception of a few oddities of dress and an unusually large number of gaudy uniforms. The guard at the iron gate was wearing a cherry-colored tunic, white trousers, and a black steel helmet surmounted by a gold spike and a deep purple plume. He presented arms—a short and wicked looking nickel-plated machine gun—and as the gate swung wide we eased past him and stopped before broad doors of polished iron-bound oak. A brass plate beside the entrance said Kungliga Svenska Spionage.

I said nothing as we walked down a spotless white marble-floored hall, entered a spacious elevator, and rode up to the top floor. We walked along another hall, this one paved with red granite, and paused before a large door at the end. There was no one else around.

"Just relax, Mr. Bayard. Answer all questions fully, and use the same forms of address as I do."

"I'll try not to fall down," I said. Winter looked as nervous as I felt as he opened the door after a polite tap.

The room was an office, large and handsomely furnished. Across a wide expanse of grey rug three men sat around a broad desk, behind which sat a fourth. Winter closed the door, walked across the room with me trailing behind him, and came to a rigid position of attention ten feet from the desk. His arms swung up in a real elbow-buster of a salute and held it.

"Sir, Chief Captain Winter reports as ordered," he said in a strained voice.

"Very good, Winter," said the man behind the desk, sketching a salute casually. Winter brought his arm down with a snap. He rotated rigidly toward the others.

"Kaiserliche Hochheit," he said, bowing stiffly from the waist at one of the seated figures. "Chief Inspector," he greeted the second, while the third, a rather paunchy fellow with a jolly expression and a somehow familiar face, rated just "Sir."

"'Hochwelgeboren' will do," murmured the lean aristocratic-looking one whom Winter had addressed first. Apparently instead of an imperial highness he was only a high-well-born. Winter turned bright pink. "I beg your Excellency's pardon," he said in a choked voice. The round-faced man grinned broadly.
