Crossover Cover: The Adventure of the Proper Comma

 

Solar Pons’ best friend and biographer Dr. Parker returns “from Thorndyke and Polton with an analysis of the capsules Mrs. Buxton had carried with her.” Thorndyke and Polton are R. Austin Freeman’s sleuth Dr. John Evelyn Thorndyke and his lab technician Nathaniel Polton.

This crossover, and hundreds more like it, are included in my book Crossovers Expanded: A Secret Chronology of the World Volume 3, which will be published by Meteor House! Like the first two volumes, this one is an AUTHORIZED companion to Win Scott Eckert's Crossovers: A Secret Chronology of the World Volumes 1 and 2!
