The metal man started toward them, moving quietly, for all his bulk. The scent he gave off was mostly machine oil, cordite, and plastic, but underneath it all, Kham caught a whiff of something rotten and decaying. The guy stopped a few meters away.

That kind of cowboy move might work against an ordinary opponent, but it would be suicide against the coiled-spring speed of this metal man.
