Ignoring their mutual animosity,
Abe and his brother-in-law Hymie
became co-owners of a brownstone on Putnam Avenue. 

The top floor of their house went up in flames when the son of their tenant, neuralgia–sufferer Mrs. Kelvin played with matches while she gossiped in the kitchen.

But Abe was left with a souvenir.
As he saved the Kelvin boy, a shard of fallen skylight seared a permanent crater into his hand.

Mrs. Kelvin was not the only one with an aching head.
Hymie and Abe realized that they no longer had fire insurance-the bill had gone unpaid because of their disagreement about who was responsible for its postage stamp.
