Who is the boy who dies?

Dr. Steward's hands gripped the table tightly until his knuckles turned white with rage, but he had to control himself; these people wouldn't tolerate much mischief from him if he started yelling at them or threatened to expose the scandal of a gambler's death.

"And what are they going to do? Hide the corpse forever? Throw it into a volcano? That boy should be back home in three months. Explain to me how we're going to hide that." Steward was reluctant to cover up the whole matter; with the data before them, no one could accuse him of anything or doubt his impeccable work, but if they were talking about hiding a dead person, that was being an accomplice to a crime.

A man Steward didn't know and who had been staring distractedly out the window turned around with an energetic air. He had a certain military bearing and a stern look.
