Alarm

The door was opened and they looked out.

She was very surprised and he looked very worried.

Who was it, who was looking through that door?

Who had seen them, did they know?

No, no one could know what they did tonight.

So they went quickly to find out more.

Silently they crept to that back door, their shovels in hand.

But no one was there.

They sneaked through the house to see if anyone had been there.

Check the windows, the doors, the rooms.

Nothing, the doors were locked, the windows closed, and the rooms empty.

So how had the door opened? 

they go back to the door and looked around.

There, what is that hidden by the frame?

She slowly picked up the object and finally, it all made sense.

That stupid cat had nearly given them a heart attack.
