Dr. Lord laughed and said:
"Yes, I had a Spanish visitor the day before yesterday. But it wasn’t a man. It was a lady."
"I found a new kind of fluid in this little syringe, doctor," said Nick, adroitly changing the subject.
"Indeed?"
"Yes. You know that people who understand surgical instruments usually go in for a little chemistry, too. When I examined the cylinder of this syringe I noticed a small quantity of colorless liquid in it; so I took it out and analyzed it."
The doctor was now becoming interested again, and Nick continued:
"I found it was a terrible poison."
"What?" cried Dr. Lord.
"Yes, doctor. That little syringe contained enough poison to kill a dozen men."
"You astonish me!" said the doctor.
