This is a longer story (32,000 words) about a down-on-his-luck prospecting guide who lands very rich clients just when he really needs them.
The story is about Audee Walthers a man who once lived on Earth but now makes his home on Venus. Trouble is Walthers is dying and needs a large influx of money for a liver transplant. He is lucky enough to meet and contract with a rich couple on an adventure holiday from Earth. The couple wants to go on a prospecting tour but, on Venus, it's not mineral wealth that people are prospecting for - it's archeology. Venus was once populated by a race dubbed the Heechee, who once lived in under-ground tunnels, and who mysteriously left the planet. Finding unexplored tunnels and any artifacts can make a person instantly wealthy.
There are numerous lies and double-crosses in the story. This is what I look for in a SF story; I want to see real people struggling to make a living doing the kinds of things that people do right here on earth; like trying to out-fox each other for money. I don't need FTL travel and I don't need aliens mucking up the story to make it work for me but I do love the hardware. Give me space and a bucket-of-bolts space ship and I'm hooked.
I came to the story via a wonderful on-line service provided by Best Science Fiction Stories, conveniently found at:

If you decide to subscribe you'll get near-daily updates from them. The emails themselves are wonderful; not only do they tell you a bit about the story and where to read it but they will also give you a bit of background on the author and the story itself, like if the story is part of a much larger series of novels, if it won any awards and if it was collected in book form along the way. I highly recommend the service.
