The actor who played Garak in DS9 was Andrew Robinson. When he got the acting role, he wrote 200 pages of Garak's backstory. His use of this as a guide for his acting is probably a big reason why Garak's character has so much depth.
Most of that backstory was officially canonised by the head Trek writers. Robinson used it to write a novel, A Stitch in Time, in which Garak writes an autobiographical letter to Julian Bashir.
@InvaderXan I can't believe there's no audio-book version of this.
A book that takes the form of a letter written by a well-loved character with a distinctive voice?
Publishers should automatically make audiobooks in that scenario.
@InvaderXan Oh. Looks like there's a Change Dot Org petition asking the publisher to make Garak's book an audiobook.
So I guess it'll never happen.
