"Quite so.... Anything fresh?"
Loreuil smiled. "I have got your man."
"Sure of it?"
Loreuil seated himself next Juve. He spoke low.
"He calls himself Butler... says he is Canadian.... He declares he has been in London some time: it is a falsehood. I recognise him perfectly. I had already seen him at Châlons, when he had a connection with the singer Nichoune, and we suspected him of being the author of the leakages in the offices of the Headquarters Staff."
"That is Corporal Vinson, then?"
"Consequently you must intervene," said Loreuil.
Juve reflected. After a short silence he said:
"Intervene! You go too fast. Remember we are in a foreign country, and there is no question of a common law crime: Vinson is not accused of murder, simply of treason.
"I like that word 'simply,'" remarked Loreuil ironically.
