The Morose Mistress: The Hot Dog Detective (A Denver Detective Cozy Mystery)

Mark MacFarland had no use for politics when he was homeless on the streets of Denver. Now that he is struggling to pull himself back into regular society, he still finds politics a necessary evil he'd rather avoid. But when his friend Jerry Baker asks him to find evidence that a restaurant waitress did not kill her boss, he finds himself right in the middle of political intrigue. It turns out that the restaurateur is running for the U.S. Senate. Was he killed for political reasons...or was he killed by the waitress, the would-be politician's mistress?
