It seems unlikely that this particular species will break under interrogation as quickly as the other captives, as we believe it was specifically intended to serve as an infiltrator. Still, perhaps if we use more aggressive techniques, we can...coax...it into revealing additional information about how the aliens arrived here.
Capturing one of the invaders' infiltration specialists has proven both illuminating and disturbing. Although at first glance they resemble the human form, and are trained to communicate in a range of terrestrial languages, this specimen is far from human. We had assumed its role as an infiltration unit would preclude us from gaining anything of value during our interrogation. However, as it turns out, the captive was surprisingly...pliable once we began the procedure.
Aside from its primary role as a reconnaissance and infiltration specialist, the Thin Man also proved to be quite familiar with the alien's navigation systems and celestial cartography. The information gained from this interrogation is of crucial importance to our efforts in reverse engineering the alien navigational computers and related systems.
