That meant that he was alive. Freyberger was convinced that the man seen by Hellier was Klein. If Gyde were alive, then he must have been staying here at No. 18 St Ann’s Road. Klein had also been staying here. Therefore Gyde and Klein were working in collusion.

That would mean that Sir Anthony Gyde had entered into a partnership with this man, Klein—for what purpose?

For the purpose of murdering some unknown man in a cottage on the Fells of Cumberland, and doing it in such a manner that Klein would appear to be the victim and he, Sir Anthony Gyde, the murderer.

By extension it would mean that Lefarge, long ago, had entered into a similar partnership with Müller. The thing was preposterous.
