Its attempt was succeeding, at least partially. The Potomac was still there, but quite a lot of it was not in the river bed any more. Instead, it had gone into the air, which was so humid by now that Malone was willing to swear that it was splashing into his lungs at every inhalation. Resisting an impulse to try the breast-stroke, he stood in the full glare of the straining sun, just outside the Senate Office Building. He looked across at the Capitol, squinting his eyes manfully against the glare of its dome in the brightness.

The Capitol was, at any rate, some relief from the sight of Thomas Boyd and a group of agents busily grilling two technicians. That was going on in the Senate Office Building, and Malone had come over to watch the proceedings. Everything had been set up in what Malone considered the most complicated fashion possible. A big room had been turned into a projection chamber, and films were being run off over and over. The films, taken by hidden cameras watching the computer-secretaries, had caught two technicians red-handed punching errors into the machines. Boyd had leaped on this evidence, and he and his crew were showing the movies to the technicians and questioning them under bright lights in an effort to break down their resistance.

But it didn't look as though they were going to have any more success than the sun was having, turning Washington into the Sahara. After all, Malone told himself, wiping his streaming brow, there were no Pyramids in Washington. He tried to discover whether that made any sense, but it was too much work. He went back to thinking about Boyd.

The technicians were sticking to their original stories, that the mistakes had been honest ones. It sounded like a sensible idea to Malone; after all, people did make mistakes. And the FBI didn't have a single shred of evidence to prove that the technicians were engaged in deliberate sabotage. But Boyd wasn't giving up. Over and over he got the technicians to repeat their stories, looking for discrepancies or slips. Over and over he ran off the films of their mistakes, looking for some clue, some shred of evidence.

Even the sight of the Capitol, Malone told himself sadly, was better than any more of Boyd's massive investigation techniques.

He had come out to do some thinking. He believed, in spite of a good deal of evidence to the contrary, that his best ideas came to him while walking. At any rate, it was a way of getting away from four walls and from the prying eyes and anxious looks of superiors. He sighed gently, crammed his hat onto his head and started out.

Only a maniac, he reflected, would wear a hat on a day like the one he was swimming through. But the people who passed him as he trudged onward to no particular destination didn't seem to notice; they gave him a fairly wide berth, and seemed very polite, but that wasn't because they thought he was nuts, Malone knew. It was because they knew he was an FBI man.

That was the result of an FBI regulation. All agents had to wear hats. Malone wasn't sure why, and his thinking on the matter had only dredged up the idea that you had to have a hat in case somebody asked you to keep something under it. But the FBI was firm about its rulings. No matter what the weather, an agent wore a hat. Malone thought bitterly that he might just as well wear a red, white and blue luminous sign that said FBI in great winking letters, and maybe a hooting siren, too. Still, the Federal Bureau of Investigation was not supposed to be a secret organization—no matter what occasional critics might say. And the hats, at least as long as the weather remained broiling, were enough proof of that for anybody.

Malone could feel water collecting under his hat and soaking his head. He removed the hat quickly, wiped his head with a handkerchief and replaced the hat, feeling as if he had become incognito for a few seconds. The hat was back on now, feeling official but terrible, and about the same was true of the fully-loaded Smith & Wesson .44 Magnum revolver which hung in his shoulder holster. The harness chafed at his shoulder and chest and the weight of the gun itself was an added and unwelcome burden.

But even without the gun and the hat, Malone did not feel exactly chipper. His shirt and undershirt were no longer two garments, but one, welded together by seamless sweat and plastered heavily and not too skillfully to his skin. His trouser legs clung damply to calves and thighs, rubbing as he walked, and at the knees each trouser leg attached and detached itself with the unpleasant regularity of a wet bastinado. Inside Malone's shoes, his socks were completely awash, and he seemed to squish as he walked. It was hard to tell, but there seemed to be a small fish in his left shoe. It might, he told himself, be no more than a pebble or a wrinkle in his sock. But he was willing to swear that it was swimming upstream.
