"We have another job for you, Marine."

"Sir! Yes sir!"

"You're going to be part of something very special."

"Sir! The Marine Raiders are already a very special part of a very special Corps, sir!"

"That's not what I mean. I mean that this assignment is . . . unusual." The major looks over at the colonel. He is not sure how to proceed.

The colonel puts his hand in his pocket, jingles coins, then reaches up and checks his shave.

"It is not exactly a Marine Corps assignment," he finally says. "You will be part of a special international detachment. An American Marine Raider platoon and a British Special Air Services squadron, operating together under one command. A bunch of tough hombres who've shown they can handle any assignment, under any conditions. Is that a fair description of you, Marine?"

''Sir! Yes, sir!''

"It is a very unusual setup," the colonel muses, "not the kind of thing that militarymen would ever dream up. Do you know what I'm saying, Shaftoe?"

"Sir, no sir! But I do detect a strong odor of politics in the room now, sir!"

The colonel gets a little twinkle in his eye, and glances out the window towards the Capitol dome. "These politicians can be real picky about how they get things done. Everything has to be just so. They don't like excuses. Do you follow me, Shaftoe?"

''Sir! Yes, sir!''

"The Corps had to fight to get this. They were going to make it an Army thing. We pulled a few strings with some former Naval persons in high places. Now the assignment is ours. Some would say, it is ours to screw up.

"Sir! The assignment will not be screwed up, sir!"

"The reason that son of a bitch MacArthur is killing Marines like flies down in the South Pacific is because sometimes we don't play the political game that well. If you and your new unit do not perform brilliantly, that situation will only worsen."

''Sir! You can rely on this Marine, sir!''

"Your commanding officer will be Lieutenant Ethridge. An Annapolis man. Not much combat experience, but knows how to move in the right circles. He can run interference for you at the political level. The responsibility for getting things done on the ground will be entirely yours, Sergeant Shaftoe."

''Sir! Yes , sir!''

"You'll be working closely with British Special Air Service. Very good men. But I want you and your men to outshine them."

"Sir! You can count on it, sir!"

"Well, get ready to ship out, then," the major says. "You're on your way to North Africa, Sergeant Shaftoe."

Chapter 12 LONDINIUM

The massive British coinage clanks in his pocket like pewter dinner plates. Lawrence Pritchard Waterhouse walks down a street wearing the uniform of a commander in the United States Navy. This must not be taken to imply that he is actually a commander, or indeed that he is even in the Navy, though he is. The United States part is, however, a safe bet, because every time he arrives at a curb, he either comes close to being run over by a shooting-brake or he falters in his stride; diverts his train of thought onto a siding, much to the disturbance of its passengers and crew; and throws some large part of his mental calculation circuitry into the job of trying to reflect his surroundings through a large mirror. They drive on the left side of the street here.

He knew about that before he came. He had seen pictures. And Alan had complained of it in Princeton, always nearly being run over as, lost in thought, he stepped off curbs looking the wrong way.

The curbs are sharp and perpendicular, not like the American smoothly molded sigmoid-cross-section curves. The transition between the side walk and the street is a crisp vertical. If you put a green lightbulb on Waterhouse's head and watched him from the side during the blackout, his trajectory would look just like a square wave traced out on the face of a single-beam oscilloscope: up, down, up, down. If he were doing this at home, the curbs would be evenly spaced, about twelve to the mile, because his home town is neatly laid out on a grid.

Here in London, the street pattern is irregular and so the transitions in the square wave come at random-seeming times, sometimes very close together, sometimes very far apart.

A scientist watching the wave would probably despair of finding any pattern; it would look like a random circuit, driven by noise, triggered perhaps by the arrival of cosmic rays from deep space, or the decay of radioactive isotopes.

But if he had depth and ingenuity, it would be a different matter.

Depth could be obtained by putting a green light bulb on the head of every person in London and then recording their tracings for a few nights. The result would be a thick pile of graph-paper tracings, each one as seemingly random as the others. The thicker the pile, the greater the depth.
