of a curious thing that happened to me this morning. At first I thought I would tell the police, but it occurred to me they might misunderstand; and I decided to place the matter before you to act upon as you saw fit."
Plainly he was uncertain as to how the subject should be broached, and Markham waited patiently with an air of polite indulgence.
"I phoned the Greene house as soon as I made the—ah—discovery," Von Blon went on hesitantly. "But I was informed you had left for the office; so, as soon as I had lunched, I came directly here."
"Very good of you, doctor," murmured Markham.
Again Von Blon hesitated, and his manner became exaggeratedly ingratiating.
"The fact is, Mr. Markham, I am in the habit of carrying a rather full supply of emergency drugs in my medicine-case. . . ."
"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.
