A few minutes later the man was at her door.

Would we want to simply show up at their door?

I had only put the phone down two minutes before, and now he was at my door.

Do you think I want your death at my door?

Early the next morning he turned up at her door.

She always seemed to know who was at her door.

But half an hour later I was back at her door.

At her front door she called out in a clear voice.

We were at its door when a man called out behind us.

Maybe she'd even find them at her door one night when she came home.

He thought very hard to hear every word under the door.

Maybe he could find the woman who had left the note under his door.

If there was someone out in the hall, they'd see the light under the door.

There wasn't even a line of light from the hall under the door.

If there's a light on in the room, you can see it under the door.

There was light inside, and they could easily see under the door.

"A note came under the door while you were gone."

He could see a thin line of light under the door now.

She could see the thin line the light made under his door.

There was a bar of light under his own door.
