"Alvin Goodfellow

PI to the stars

The best you'll find

On the Moon, Venus, or Mars..."

Or at least that is how the jingle goes for the ads Alvin constantly runs on the radio.

No one...human.

How does he solve such a labyrinth of politics, police, and potential artificial intelligence?

Another of the Alvin Case Files, and the last of Leah Cutter's Year of Mystery!
