Smell

Where is it coming from?
It smelled like a sewer in the house. It smelled like a sewer in the garden. It smelled like a sewer in the street. All three places smelled as strongly as each other.
He got on a bus. It smelled like a sewer.
"Can you smell that?" he asked a passenger who moved away from him.
Maybe I smell?
Maybe, indeed. The smell stayed with him all day.
He returned home and showered thoroughly. He put on fresh clothes. Still there was a sewer smell.
He tried to eat his dinner, something the smell made quite challenging.
He went to bed and drifted off as the sewer smell hung over him.
