Worried about his own mother's tombstone, the taxi driver asks if they could take a detour. John agrees, but he's not happy about it.
They take a second detour to the tombstone salesroom across the street.
It's called Avram Breed and Sons.
While wandering around the memorials, John spies an angel dressed in mistletoe, cedar boughs, and Christmas tree lamps. He asks how much.
The salesman informs him it's not for sale on account that its one hundred years old. The salesman, it turns out, is Marvin Breed, brother of Dr. Asa Breed.
John comments that it's a small world. Marvin says it is "[w]hen you put it in a cemetery" (31.16).
