The Middle of Things — XXI. The Marseilles Meeting
(1922)
“ The man who shared the secret with Ashton is certainly the man whom Armitstead saw with him in Paris. He is probably the man whom Hyde saw leaving Londsdale Passage, just before Hyde found the body. And he is without doubt the murderer, and is the man to whom this claimant fellow is acting as cat's-paw. And—who is he?" "There must be some way of finding that out," observed Mr. Perkwite. "If your theory is correct, that this claimant is merely a man who is being put forward, then surely the thing to do is to get at the person or persons behind him, through him!" ”
