Knight's Scheme, The Blackgaard Chronicles #5

The scheming Dr. Regis Blackgaard continues his fevered pursuit of the Applesauce program and access to Whit’s End. This time, on a trip to Chicago, Whit and Connie get caught up in a dangerous mystery involving a stolen laptop, the Department of Defense, and some familiar (but not very friendly) faces.

This fifth book of The Blackgaard Chronicles series introduces more of the story beyond the Adventures in Odyssey audio dramas.
