The "
nom de
crime"
(?) of James Bolivar DiGriz, better
known as
Slippery Jimmy DiGriz. He used to be a very
successful intergalactic criminal of varying sorts, until he was
caught by
The Special Corps, and
convinced to
work for them (
set a thief to catch a thief, etc). He has various
skills including
disguise,
weapons,
electronics, and a
very quick brain (definitely not a
moron, as one above
writeup used to say)
He's the main character from a series of books by Harry Harrison, starting with the not-terribly-imaginatively named The Stainless Steel Rat, and continued with The Stainless Steel Rat's Revenge, and The Stainless Steel Rat goes to Hell. There may be others, but I haven't seen them.
