Did a re-read on David Mack's excellent Mirror Universe: Rise Like Lions
. Currently skimming through Andrew J. Robinson's A Stitch in Time
and reading a few short stories from Joyce Carol Oates.
I settled on proceeding with le Carré, and I'm currently waiting for a used copy of the Karla
trilogy -- consisting of Tinker Tailor Soldier Spy
, The Honourable Schoolboy
, and Smiley's People
-- to arrive so I can dig in.
