“You mean you’ve told the papers — I mean Liberdad — that O’Rourke is hiding something?”

“I t-told the t-truth,” said Caldwell with dignity. “And now I’m going to p-prove it. You’re an outsider, Hakluyt, s-so you’re an independent witness. I want you to c-come along t-tonight and s-see for yourself.”

I almost said, “You must be out of your mind!” And then I didn’t. Because it occurred to me, watching Caldwell’s wild expression, that that was very probably true.

I changed the remark to, “Well, what do you think does go on there?”

“All k-kinds of vice, Hakluyt! I’ve s-seen it. And if you c-come with me tonight, I’ll sh-show you.”

I frowned and didn’t reply for a moment. It was logical, of course, that there would be at least a few prostitutes operating out of the shantytowns — poverty dictated it. But to accuse el Jefe himself of graft, and to accuse — most likely with justice — a few local police officers of turning a blind eye, were two totally different things.

“You’ll come with me?” he insisted hotly. I yielded with a sigh, and he rose and shook my hand warmly.

“You’ll s-see!” he said.

I went back, frowning, to the traffic department after arranging to see Caldwell at one of the shantytowns at eightp.m., and called in on Angers to consult him about Caldwell’s condition.

He greeted me with comparative warmth, for him. “We’re going all-out on this plan of yours,” he said. “Well done!”

I scowled; this enthusiasm for what I could only regard as rubbish was getting me down. “How does Diaz feel about it?” I asked.

“Well, of course, he hasn’t got a leg to stand on. One almost has to feel sorry for him. I don’t mind saying it’s put me in a pretty sticky position, because of course while Diaz is nominally my chief, Vados is mayor of the city, and in this case it’s what he says that counts. However, I must say the argument has been a very interesting one — it’s a pity you’re not a citizen, because there’s an important principle at stake.”

“It strikes me a still more important principle would have been to make the whole damned city self-governing, instead of crossing it up with the national government.”

Angers gave his barking laugh. “They have a genius for complex things like this in Latin America, Hakluyt. You ought to try Brazil for real confusion.”

“I’ve had enough confusion to last me a lifetime. Angers, what do you make of Caldwell’s behavior lately?”

“How do you mean?”

“Well, he asked me to go and see him, and I’ve just been over there. He’s got some crazy notion in his head that O’Rourke is being paid to conceal some kind of vice-racket — at least, as far as I can make sense of what he says. I’m supposed to be going on a sort of voyeur’s tour with him this evening. Is there any foundation for this, do you suppose? Or is he just suffering from overstrain?”

“Good Lord!” said Angers, blinking. “Well! O’Rourke isn’t exactly a paragon of efficiency — that’s well-known. But I always thought he was a fairly honest man — if he weren’t, I don’t suppose Vados would tolerate him. Who’s supposed to be paying him — anyone in particular, or just individuals?”

“Search me. Frankly, I think the guy’s about to blow his top. Who’s his chief — Ruiz? Someone ought to keep an eye on him. I mean, there’s enough mud being thrown at O’Rourke already, and some of it probably ought to stick, but this is irresponsible nonsense so far as I can see.”

“Well, I don’t know. Caldwell’s young and hard-working; he’s always been the nervous type, but then one can understand that, with that stutter he suffers from. I’d be inclined to think there was something to what he says. But on the other hand it has all been denied by O’Rourke, hasn’t it?”

He made a note on his scratch pad. “I’ll say something to Ruiz, if you like. Maybe he needs a rest.”

And yet, when I met him that evening at the appointed time and place, he seemed much calmer and more in control of himself. He wasn’t alone; there were two policemen and a photographer with him. I wondered whether O’Rourke knew about the policemen — I didn’t think he would approve of them helping Caldwell to gather evidence against him.

It was cloudy tonight, but warm, and the shantytown was like a set for an experimental film as we moved into it, Caldwell authoritatively taking the lead. An air of sullen hostility met us, brooding heavy over the beaten, unweather-proofed matchboard hovels, decorated if at all with torn oil-company posters and pinup calendars from the year before last. If we had not been a formidable group, we would probably have had things thrown at us. Rotten eggs, perhaps. Or knives.

Caldwell was carrying a flashlight; as we passed a patch of ground scratched with a hoe into some kind of cultivable condition, he stabbed the beam down at the plants growing there. He said, “Look!”

I looked; I saw only a plant growing. “Th-that’s hemp,” said Caldwell. “You g-get marijuana from th-that.” His voice was tense and triumphant. “S-see, Hakluyt?”

I wasn’t surprised. In fact, I wasn’t surprised at anything Caldwell showed me during our tour. We walked in on families sleeping five to a hut, and Caldwell invited me to express disgust, which I duly did. But this was no surprise; it was inevitable, given the conditions.

Before another hut we halted, and Caldwell turned to me, indicating silence. “A s-streetwalker lives here,” he hissed in confidential tones. “Th-there are d-dozens of them!”

“There are always dozens of them!” I said irritably. So far the biggest surprise he’d sprung on me was his comparatively reasonable manner this evening, his air of confidence.

He walked up and flung back the door of the hut. The beam of his flashlight speared around the empty interior. “Off after more customers,” he said in a low tone. “See here, Hakluyt — in this box.”

His voice shook a little. I shrugged and went to see what he had found. It proved to be a crude wooden chest containing a leather whip and some boxes of contraceptives.

His eyes searched my face for a reaction. Slowly his confidence began to evaporate.

“Look, Caldwell,” I said as kindly as I could, “you’ll always get this sort of thing where there’s poverty in a big city. You can’t legislate it out of existence. It’s been tried, over and over again. I’m afraid you haven’t proved anything that wasn’t self-evident.”

He drew himself up and kicked the wooden box aside. “It was a mistake for so many people to come,” he snapped, his stutter vanishing for the moment as it seemed to when he shot out a single phrase he had been turning over in his mind beforehand. “S-sorry, Hakluyt,” he added after a moment. “I ought really t-to sh-show you what g-goes on down in S-Sigueiras’s p-place, but it’s d-dangerous to g-go th-there.”

We went back in silence to the place where our cars were parked. Caldwell was muttering something under his breath when we stopped, and I asked for a repeat.

“I said Mendoza knew,” he declared. “He wrote about it in one of his b-books. He d-described exactly the s-sort of th-thing I s-saw. Someone is c-covering it up now. Who? Why? We’ve g-got to find out, Hakluyt!”

“For the last time,” I said, taking a deep breath, “how much of this alleged vice have you seen for yourself, and how much did you just get out of some dirty story by Felipe Mendoza?”

With dignity, he drew himself up. “I t-tell you I’ve s-seen for myself!” he forced out between his teeth.

“All right,” I said, losing patience. “I haven’t. And if nothing worse goes on than what you’ve demonstrated this evening, then all I can say is that this is one of the most moral places I’ve ever set eyes on. Good night!”

I walked away to my car, fuming, feeling his hurt stare following me.

Baseless or not, Caldwell found a willing audience for his accusations in other people than me.
