"What do you make of it, Professor?" he asked.
"Is it poison!" said Quarles interrogatively.
The doctor had already examined the glasses on the table.
"I can find no signs of poison," he said. "And two hours ago the man was alive."
"That is according to the servant," I said. Masini was not in the room at this time.
"There is no reason to doubt the statement, is there?" the doctor asked.
"No, but we have not yet corroborated it," I returned.
Quarles was already busy with his lens examining the dead man's shirt front.
"You, have begun trying to find out who killed him before I have pronounced upon the cause of death," said the doctor. "I am inclined to think it is poison, but—"
"He didn't inject a drug, I suppose!" said Quarles.
