"Earthman Gary Towler is treated like a pariah; for his task as chief interpreter for the corrupt and tyrannical Nuls makes other humans avoid him as a traitor.
Nor is he trusted by the three-armed mammoth rulers themselves. The leaders realize that gary knows too much.
When the humans leading the underground rebellion demand Gary's aid or his life, he is caught between two untrustful forces. And his only way out is to make himself into a one-man third force against two world's plotters."
