There's also a letter from Hakeev and some indication that the person who hid the message for you under the rock and tipped you off about the base is someone with Tal Shiar Access codes.
Hmmm. I see my guess about the third part may be only 1/2 right.
Someone with Tal Shiar access who doesn't like Tal Shiar, or perhaps more accurately, doesn't like what the Tal Shiar had become under Hakeev. I think we are seeing another "friend" unaccounted for from Hafir...Commander Janek.
