Short story id please.

These were both contained in one of those Alfred Hitchcock paperbacks that arnt as far as i know episode adaptations.

One story was about a landfill guy who worked for the mob. The capper being that his landfill was going to be unearthed and used for apartment buildings.

Another about a guy trying to hide a gun. He hides it in his toilet watertank i think. The capper was a cop going there to look because “That’s always where they try and hide it”
