Yes both the signed & 1st edition have the same dust jacket with just one ISBN but inside they have both listed.

Also the Signed limited did come with a slipcase.

:wtf: Note the signature page lists the title as "UNDER COVER OF DARKNESS"

The proof is Kingdom of Fear....

I don't know where that 978-0-88733-017-9 # came from... It is not in any of my copies.
This is what is printed in the books.

Seems your publication date & ISBN# are incorrect. The proof, 1st edition & Signed limited all show ISBN as 0-88733-018-5
