Green for Danger

⚖The case for it

A hospital crowded with the wounded, and one patient dies under anesthesia by someone's intent. The whodunit machinery does grind on, and yes, every white coat gets a spell under the lamp. But hold each suspect up and Brand has done the harder job: she keeps all six plausibly capable of it, which is where most fair-play writers quietly cheat. She hands you the full record of that night, lets you check her arithmetic, then still catches you flat-footed. Set against a ward of real bodies, one chosen death lands with more grief than the genre usually manages.

✕The case against

Brand's six suspects exist to be suspected; inner lives extend exactly as far as the puzzle requires. Suspicion rotates mechanically through the closed circle, each nurse and doctor taking a turn as presumptive murderer, and the operating-theater evening gets re-narrated until you could perform the anesthesia yourself. If the form itself doesn't delight you, the clockwork is all there is.
