The Stranger in Bond Street

"By some mysterious means the police got to know of your friend's intended visit to Brussels to obtain his letters. Therefore, it was too dangerous for him to go to the Poste Restante, or even to send anyone there. The Brussels police were watching constantly. How they have gained their knowledge is a complete mystery."

"Who sent you to me?"

"A friend of Mr. Henfrey. My instructions are to see you, and to convey any message you may wish to send to Mr. Henfrey to him direct in Malines."

"I'm sure it's awfully good of you," Dorise replied. "Does he know you are here?"

"Yes. But I have not met him. I am simply a messenger. In fact, I travel far and wide for those who employ me."

"And who are they?"

"I regret, but they must remain nameless," said the girl, with a smile.

Dorise was puzzled as to how the French police could have gained any knowledge of Hugh's intentions. Then suddenly, she became horrified as a forgotten fact flashed across her mind. She recollected how, early in the grey morning, after her return from the ball at Nice, she had written and addressed a letter to Hugh. On reflection, she had realized that it was not sufficiently reassuring, so she had torn it up and thrown it into the waste-paper basket instead of burning it.

She had, she remembered, addressed the envelope to Mr. Godfrey Brown, at the Poste Restante in Brussels.
