I understand from Inspector Mitchington here that on the evening of his arrival Brake was away from the Mitre Hotel for two hours.

During that time, he was somewhere--with whom?
Probably with somebody who got the secret out of him, or to whom he communicated it.

For, think!--according to Glassdale, who, we are quite sure, has told the exact truth about everything, Brake had on him a scrap of paper, on which were instructions, in Latin, for finding the exact spot whereat the missing Saxonsteade jewels had been hidden, years before, by the actual thief--who, I may tell you, sir, never had the opportunity of returning to re-possess himself of them.

Now, after Brake's death, the police examined his clothes and effects--they never found that scrap of paper! And I work things out this way.

Brake was followed into that gallery--a lonely, quiet place--by the man or men who had got possession of the secret; he was, I'm told, a slightly-built, not over-strong man--he was seized and robbed of that paper and flung to his death.
