“There are one or two—very few—on record. Professor Gourbeil, the well-known alienist of Lyons, has observed two patients who recovered. But the majority of cases where orosin has been administered were found incurable. The mind is blank, the memory completely destroyed, and the general health so undermined that only the strongest persons can withstand the strain.”
At once I described Gabrielle’s symptoms and general attitude, whereupon the Professor said:
“What you tell me are the exact symptoms exhibited by a person to whom a small dose of orosin has been administered. In most cases, however, such a state of mind develops into actual insanity with a homicidal tendency. Such a patient should be very carefully watched, for in ninety per cent. the chance of a cure is, alas! beyond expectation.”
CHAPTER THE EIGHTEENTH
MORE ABOUT THE MYSTERY-MAN
One very important fact I had established. Orosin was the obscure and little-known drug that had been administered to Gabrielle Tennison, as well as to myself, by the mystery-man of Europe at his palatial house in Stretton Street. Gabrielle being the weaker, was still suffering from its paralysing effects, while I, the stronger, had practically recovered.
Yet it had been intended by the daring Despujol that a fatal “accident” should now befall me! And could anything be plainer than that the fellow for whom the police were searching so eagerly was a hireling of the man De Gex who went in fear of me?
