Doom patrol ship

'What is that?' asked Natasha as everyone sense the shaking.
'It's a Doom-class police patrol ship, crap!! why are they here?' said Henry nervously
'Maybe a moron just fires a gun into the air that catches their attention and decides to check it out at here!!!!' said Emily looking at Henry furiously.
'She cannot be discovered if they search the room, quick open the basement door, Miss Romanoff please stay quietly for our sake, no matter what happened don't do anything, if you are blown, we screw.' said Emily as Mike open the hidden door behind the bookshelf. Natasha knows she can't do anything. She enter the basement as Emily demanded.

The basement is are composed of four concrete walls on four sides, a pipe that connects the ceiling and the ground, probably for the water. What does this basement for? asked Natasha to herself. 'It doesn't matter, what matters is the patrol outside, hope Emily can deal with them well. Natasha tried to peek through the door that connect the basement and the cabin, but the door is shut tight, clearly locked from the other side. Natasha leaned silently on the door listening to what might happen, might be useful information she don't want to miss.
