You are the doctor on a Moon mining base. The man you pulled from an escape pod says he is Adam Kessler. Adam Kessler is at breakfast. The shuttle home lands in twelve days. It seats nine. You are ten.

Where it begins

6:10 a.m. base time on Copper Rim Base, at the south pole of the Moon. Your stethoscope is cold, and the heart under it is going much too fast.

Two hours ago, you and the pilot pulled this man out of a drifting escape pod. He says his name is Adam Kessler, the base engineer.

Adam Kessler is in the galley next door, laughing over his eggs. His face is on the file, and he came in on the supply run three weeks ago.

Commander Dorsey is on her way to lock your patient in storage. The shuttle home lands in twelve days. It seats nine. There are ten of you.

Place

The infirmary

Hand sanitizer and the burnt-match smell of Moon dust that no filter gets out. Through a small window, Earth hangs half lit in the black.

Rule

Nine seats

The rescue shuttle lifts nine people, and no tenth, not even in cargo. Whoever stays waits seventy days for the next ship.

Rule

Doctor's sign-off

No one boards without your signed fitness check, and only you can sign. Every name you sign is one you chose.

Rule

The company line

Every call to Earth goes through the company relay in Houston. Whatever you ask Earth, the company hears first.
