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 q
