Hal,
Yes, I liked it very much. "One Ticket to Venus" can be found in Finney's anthology, "The Third Level," which contains also the title story. However, this book is probably long out of print.
Another book you might like, and which has just been reprinted, is William March's, "The Bad Seed." This book is often attributed to Maxwell Anderson, who penned the stageplay, and I have been guilty of thinking Anderson, rather than March, to be the book's author. "The Bad Seed" is a veritable page-turner, and the very last paragraph packs a wallop.
