One thing I learned while writing this book is that “hearse” is a generic name for a funeral vehicle. It’s not a company or brand. Most hearses in North America are built on Cadillac or Lincoln chassis. Originally the word “hearse” referred to an elaborate framework erected over a coffin and placed on a horse-drawn carriage. But these days it usually used to refer to the vehicle itself. I imagine the one driven by Sayer Burdon looks something like the one below.
