I just finished reading Mr. Mercedes (a little late to the game) and just have to mention a number of coincidences. I grew up on the West side of Cleveland, Ohio. Both my sets of Grandparents lived in the same town we did. My maternal grandmother was Elizabeth (nick-name Betty) Wharton. My maternal grandparents lived in a high-rise tower on the Lake Erie Gold Coast (just west of downtown Cleveland). They always drove Mercedes Benz autos. It was surreal when I started reading the book...of course none of the events in the book happened to me, but the coincidences were freaky.
