“No; you are innocent.”

“Ah, Gabrielle,” he cried earnestly, “how shall I ever thank you enough for clearing up the awful mystery and removing the guilty burden from my conscience?”

“I said I would convince you. Here is the letter,” and she handed the missive for their inspection.

“Did you meet as arranged?” Hugh asked breathlessly, recognising his brother’s handwriting.
