'Is he lying?' Khan wondered as his first instinct compelled him to refute that statement.
Still, Khan quickly realized that the Orlats' only reason to lie would involve their partaking in the theft. The two aliens would probably remain silent even in front of proper threats in that case, which forced Khan to consider other options.
Sher's revelation sounded far from misleading. Khan had a clear idea of the human's greed and cruelty, and everything he had learnt about the investigation hinted at the presence of spies.
However, Khan also felt pretty sure that Luke's family had sent its best investigators to gather information about the theft. There probably wasn't any spy among them, which put Khan in a pickle.
The Orlats could be lying, and the humans might have hindered the investigation. Both options had reasonable arguments, leaving Khan unable to find the truth.
