h kills like lightning and leaves no trace, the famous recipe
bequeathed from age to age, through the emperors and the popes, down to
these present times of middle-class democracy."

As he spoke he ended by smiling, for he was inclined to be somewhat
sceptical on the point, despite the covert terror with which he was
inspired by racial and educational causes. However, he quoted instances.
The Roman matrons had rid themselves of their husbands and lovers by
employing the venom of red toads. Locusta, in a more practical spirit,
sought poison in plants, one of which, probably aconite, she was wont to
boil. Then, long afterwards, came the age of the Borgias, and
subsequently, at Naples, La Toffana sold a famous water, doubtless some
preparation of arsenic, in phials decorated with a representation of St.
Nicholas of Bari. There were also extraordinary stories of pins, a prick
from which killed one like lightning, of cups of wine poisoned by the
infusion of rose petals, of woodcocks cut in half with prepared knives,
which poisoned but one-half of the bird, so that he who partook of that
half was killed. "I myself, in my younger days," continued Prada, "had a
friend whose bride fell dead in church during the marriage service
through simply inhaling a bouquet of flowers. And so isn't it possible
that the famous recipe may really have been handed down, and have
remained known to a few adepts?"

"But chemistry has made too much progress," Pierre replied. "If
mysterious poisons were believed in by the ancients and remained
undetected in their time it was because there were no means of analysis.
But the drug of the Borgias would now lead the simpleton who might employ
it straight to the Assizes. Such stories are mere nonsense, and at the
present day people scarcely tolerate them in newspaper serials and
shockers."

"Perhaps so," resumed the Count with his uneasy smile. "You are right, no
doubt--only go and tell that to your host, for instance, Cardinal
Boccanera, who last summer held in his arms an old and deeply-loved
friend, Monsignor Gallo, who died after a seizure of a couple of hours."

"But apoplexy may kill one in two hours, and aneurism only takes two
minutes."

"True, but ask the Cardinal what he thought of his friend's prolonged
shudders, the leaden hue which overcame his face, the sinking of his
eyes, and the expression of terror which made him quite unrecognisable.
The Cardinal is convinced that Monsignor Gallo wa
