The following excerpt has been taken from The Invisible Man by H. G. Wells.
"Draw the bolts," said the man with the black beard, "and if he comes—" He showed a revolver in his hand.
"That won't do," said the policeman; "that's murder."
"I know what country I'm in," said the man with the beard. "I'm going to let off at his legs. Draw the bolts."
"Not with that blinking thing going off behind me," said the barman, craning over the blind.
"Very well," said the man with the black beard, and stooping down, revolver ready, drew them himself. Barman, cabman, and policeman faced about.
How does the sentence-Not with that blinking thing going off behind me- fit here?
