Letter from Russian Nobleman

“Two days ago I received the letter which I now read to you. Neither address nor date is attached to it.” (Dr Percy Trevelyan)
“A Russian nobleman who is now resident in England [it
runs], would be glad to avail himself of the professional
assistance of Dr. Percy Trevelyan. He has been for some
years a victim to cataleptic attacks, on which, as is well
known, Dr. Trevelyan is an authority. He proposes to call at
about a quarter-past six to-morrow evening, if Dr. Trevelyan
will make it convenient to be at home.”
