dull, if you know what I mean. I head back to California every couple of weeks for a few days. But overall, Iâve been here longer than just about anybody. Even longer than that old professor in the campsite next to yours.â
âYou mean Professor Townsend?â Joe asked.
âYeah, him,â Perez replied. âHeâs a crab, but his daughter is nice. Her name is Diane.â
âWhat does the professor do here?â Joe asked.
âI donât know,â Perez said. âHeâ Hey, why are we standing out here in the middle of the road? You guys want to come over to my place and have a soda? Itâs right over there.â
The three walked over to Perezâs campsite as he continued to talk about Professor Townsend. âIâm not sure what he does around here,â Perez said. âHe and Diane go off almost every day. I see them here and there in the park. Or rather I see their truck pulled over on the side of the road. I guess theyâre out in the desert someplace, doing research or something. I tried to talk to him one day about what he does, but he almost snapped my head off.â
âWhat about Diane?â Frank asked. âIs she easier to talk to?â
Perez shrugged. âI guess,â he said. âBut she seems a little afraid of him.â
âWhat do you mean?â Frank asked.
âI mean she clams up when heâs around,â Perez said.
When they reached Perezâs campsite, Joe saw litter under the picnic tableâa banana peel and some used paper plates. Maybe heâs a famous artist, Joe thought wryly, but he needs to learn some housekeeping skills. And he doesnât seem to have much respect for the great outdoors.
âDoes Diane talk much when her dad isnât around?â Frank asked.
âYeah, I guess,â Perez said, opening an ice chest. âYou guys want a cola? Thatâs all Iâve got.â
âNo, thanks,â Joe said.
âA cola would be fine,â Frank said. âSo, what does Diane have to say when her dad isnât around?â
Perez handed a cold, wet can to Frank and said, âWell, she told me heâs doing some kind of medical research. Something to do with using cacti and other desert plants as sources for medicine. I couldnât get her to be more specific than that. I do know they leave every few days, always at night.â
âAt night?â Frank asked.
âYeah,â Perez said. âThey take off about sunset in their pickup, and they leave the camp trailer behind. They come back a day or two later.â
âWhen was the last time they left?â Joe asked.
Perez looked thoughtful for a moment. âThree days ago,â he said. âThey came back about noon today, just before you arrived.â
âMan,â Joe said, âyou notice everything, donât you?â
Perez brightened. âArists are observant. I keep my eyes and ears open. That way I donât miss any of the action.â
âWho else besides you and Professor Townsend has been here for a long time?â Frank asked.
Perez thought for a moment. âNobody, really,â he said. âThereâs a couple down on the end who were here for a week and then gone for maybe a month. I think they were in Mexico. Theyâve been back about a week now. But thatâs about it. Everybody else is just passing through, more or less.â
Frank looked carefully at Perez, trying to guess what he was thinking. Frank wondered if he was just a busybody or if his nosiness had some other purpose. âWell,â Frank said, âweâd better get back. Joe, I think youâve got some hot dogs to put on the grill. That charcoal should be the right temperature by now.â He shook hands with Perez. âThanks for the soda.â
On the way back to their campsite, Frank said, âThat guy could be a good source of information if we need it.â
Joe nodded.
