"Well?" asked the former of Drevenoff.
"You are Mr. Ashton-Kirk?"
"I am."
"I was sent to fetch you at once to Dr. Morse's place on Fordham Road, Eastbury."
"Who sent you?"
"Miss Corbin."
Ashton-Kirk looked at the young man; his face was pale, his eyes were brilliant with excitement.
"Has anything happened?"
"Dr. Morse has been murdered."
