A few more have just popped up (I got all of the last lot on the auxiliary account I keep for the free stuff I'm unlikely to read but one day might try so these are definitely new).
They're mostly shorter works, but the first 3 seem to be uncollected, at least not in the freebied collections.
Babe on Board - A Harry McGlade/Jack Daniels Mystery didn't spot it in either the JD collection or the Crime one
Exposed - A Thriller (Chandler Series) says it's a short novel
Wild Night is Calling didn't spot it in any of the collections
KILLERS - A Psycho Thriller available in Killers Uncut and Serial Killers Uncut
The Screaming (in at least 2 of the horror collections)
