The Travelling Vampire Show by Richard Laymon

Though gloomy with clouds, it is a hot, August morning in the summer of 1963. All over the rural town of Grandville, tacked to power poles and trees, taped to store windows, blowing along the sidewalks, fliers have appeared announcing the mysterious one-night-only performance of The Traveling Vampire Show.

The show will feature Valeria, the only known vampire in captivity. According to the fliers, she is a gorgeous, stunning beauty. In the course of the performance, she will stalk volunteers from the audience, sink her teeth into their necks and drink their blood!

For three local teenagers who see the fliers, this is a show they don't want to miss. But they may have to.
Though they can probably scrape up the price of admission, other obstacles stand in the way. One problem, nobody under 18 years of age is allowed into the show. Dwight, Rusty, and Slim are only 16. Another problem, the show begins at midnight and the three teens always have to be home by then. If that weren't bad enough, the show is to take place at Janks Field -- a desolate patch of ground with a nasty history -- that has been declared off limits by their parents
The situation appears hopeless.

Though Dwight and his friends fear they won't be able to attend the actual performance of the Traveling Vampire Show, they do have the entire day to themselves. Why not hike out to Janks Field and take a look around? With any luck, they might be able to watch the crew make preparations for tonight's performance. If they're really lucky, maybe they'll get a peek at Valeria, the gorgeous vampire.
And so the three friends set off on foot for Janks Field...
Dwight is a solid, honest kid, long on common sense and loyalty to his friends. He always tries to do what's right.
Rusty is a husky guy who relishes trouble.
Slim, their long-time pal, is the brains of the outfit, a voracious reader of novels, an aspiring writer, and a girl. Also, she is sometimes too brave for her own good.

The Traveling Vampire Show is the tale, told in Dwight's own words, of what happened to him, Rusty and Slim on that hot summer day they hiked to Janks Field. It's the story of their friendship and love, their temptations, their betrayals, and their courage as they went where they shouldn't go, did what they shouldn't do...and ran into big trouble.
