In the book I am reading (H.G. Wells' The Invisible Man), a man was shot and the scene was being described, then I met the following sentence:

Adye leapt backwards, swung around, clutched at this little object, missed it, threw up his hand and fell forward on his face, leaving a little puff of blue in the air.

Adye is a policeman and was shot by the invisible man while trying to take a gun from him.

What does 'leaving a little puff of blue in the air' mean?

It is the smoke that came from the now invisible revolver.

The revolver vanished, flashed again into sight, vanished again

H.G. Wells' The Invisible Man

Cursing was sometimes called tuning the air blue so it is possible the fellow said something foul as he fell.

  • If H. G. Wells didn't intend this pun, it's a damn shame! In any event, you've installed it and I love it!
