“Emergency drugs?”
“Strychnine, morphine, caffeine, and a variety of hypnotics and stimulants. I find it often convenient——”
“And it was in connection with these drugs you wished to see me?”
“Indirectly—yes.” Von Blon paused momentarily to arrange his words. “To-day it happened that I had in my case a fresh tube of soluble quarter-grain morphine tablets, and a Parke-Davis carton of four tubes of strychnine—thirtieths. . . .”
“And what about this supply of drugs, doctor?”
“The fact is, the morphine and the strychnine have disappeared.”
Markham bent forward, his eyes curiously animated.
“They were in my case this morning when I left my office,” Von Blon explained; “and I made only two brief calls before I went to the Greenes’. I missed the tubes when I returned to my office.”
Markham studied the doctor a moment.
“And you think it improbable that the drugs were taken from your case during either of your other calls?”
