Venus] The Stellar Legion

The Stellar Legion is a short science fiction story by Leigh Brackett.
No one had ever escaped from Venus’ dread Stellar Legion. And, as Thekis the low-Martian learned, no one had ever betrayed it — and lived.
The Stellar Legion, fighting on Venus against the natives, is quite the opposite of stellar. Rather, they're the dregs of the service, the psychotic, the criminal, the dishonored. But when the young commander Lehn encounters one of his new underlings, MacIan, he senses that something about him is different.
MacIan seems like an honorable and brave soldier. Still, when it turns out that someone in their company is a traitor, and it looks like MacIan, Lehn is willing to admit that his instinct might've been wrong. But was he really wrong?
The Stellar Legion was first published in Planet Stories magazine in 1940. E-book: ePUB, 5,700 words, reading time approximately 30 min.
