Reuben is the nephew and trusted employee of John Hornby, a diamond merchant whose safe was opened and whose gems vanished, leaving behind a thumbprint that Mrs. Hornby's own Thumbograph confirmed as Reuben's. His own solicitor urges him to plead guilty and beg for mercy, a recommendation that leaves Reuben flushed and silent, and even his fiancée's devotion meets his cool, unappreciative stoicism. He matters because the story's central question is not whether the print is his but how it came to be there, and his refusal to accept the easy narrative of his own guilt keeps the case alive.
