Not until the door was firmly closed behind them did Michael speak again.

Any other response opened a door he wanted to keep firmly closed.

When the last was inside the doors were firmly closed.

Hours later the heavy police station door closed firmly behind them.

He opened his mouth as if to speak, and then firmly closed it again.

She sat opposite him in his office with the door firmly closed.

Then she took hold of the handle and firmly closed the door.

After a minute she came out, firmly closing the door behind her.

It was as if a door closed firmly in his soul.

With that, she was gone, the door closing firmly behind her.
