"We went into the room; and found the body of Sir Gregory; he was
disguised as a working-man; Vaud had disappeared. I ordered the body
to be taken upstairs, and made an examination. I then saw that Gregory
had been killed by being inoculated with the poison which Louis and I
had discovered. I recognised the cross of St. Catherine, half tattooed
on the arm; and I guessed from that how Vaud had induced Gregory to
let himself be pricked with the poisoned needle. I showed the mark to
Fanks when he came upstairs. But before doing so, I obliterated it
with a cut of the knife. I did this because I thought I might be
inculpated with the crime. I remember advising Hersham (who I did not
know was the real heir) to disguise himself as a negro so as to gain
realistic descriptions of street music. I did not do so with any
wrongful intention of connecting him with the murder. Madaline had
told me how Vaud was dressed as my negro servant; I saw that the death
had been brought about by the poisoned needle stolen from our
laboratory by Vaud; and with these two things in my head I recognised
my danger at once. I gave my feigned name to Fanks; I suggested that
the crime was the work of a secret society. Then I went back to
Turnor, and I was aware that I was being watched and could not return
to Taxton-on-Thames without being discovered.
"I consulted Turnor; he advised the voyage to Bombay, and said I ought
to send Caesar in my place, in order to get rid of him, since the
murderer of Gregory had been disguised in his livery; and also that
Caesar could send letters (already written by me) from India, in order
to keep up the deception, and baffle the police. I adopted the idea,
and, assisted by Dr. Turnor, I carried it out with great success. I
had an interview with Fanks in the character of Dr. Renshaw, and I
told him that I was going to Bombay. I then took a passage to India in
the P. and O. steamer 'Oceana'; and wired to Caesar to meet me at
Plymouth.
"Thither I went and gave the letters (purporting to be written by
myself from Bombay) to Caesar and sent him off in my place.
Afterwards, I took off my disguise, and went back to Mere Hall. I had
no idea that I had been followed by Mr. Fanks, and thinking that I had
destroyed all links with the crime in Tooley's Alley, likely to
endanger Louis and myself, I advised him to offer a reward so as to
still further avert suspicion.
