Black Service of Pathology had become the governors and policy-makers,
regimenting every aspect of the medical services provided by Earth

Dal knew that the medical training council, which would be reviewing his

that were the case, Doctor Arnquist would have said so, and directed him
to report to a ship. More likely, he thought, the Black Doctor wanted
to see him only to soften the blow, to help him face the decision that
seemed inevitable.

austere quarters of the resident pathologists. He found the proper
concourse, and moments later he was pressing his thumb against the
identification plate outside the Black Doctor's personal quarters.
