firebug

I've been over that thing time and time again, and I've felt like I was sort of a firebug myself sometimes.

The car was still there, but there was no sign of the firebug.

I saw one of them enter the old barn and wondered if the firebug was armed.

As he flashed by, the firebug raised his head and shook his fist at the plane.

If she did, shes getting to be a regular little firebug, said Chet.
