The Sweet Night — Frank Buchan

When passively suicidal capitalist Randy Crisp discovers a damsel in distress in his woodpile, he has no idea Elisha Cummings is neither as young as she appears, nor as human, though she is in distress. A lunatic vampire named Shevida believes having her will fulfill a prophecy and make him unassailable, and it will take all of Randy's smarts to get the best of Shevida and save Elisha from a fate worse than death.
