ally, as though about to take the short
cut across London Bridge, but as soon as the policeman was out of sight
he retraced his steps to the building which they had been discussing,
and turning the battered brass handle of the door, walked calmly in. On
his right and left were counting houses framed with glass; in front,
the cavernous and ugly depths of a gloomy warehouse. He knocked upon the
window-pane on the right and passed forward a step or two, as though
to enter the office. The boy, who had been engaged in the left-hand
counting house, came gliding from his place, passed silently behind the
visitor and turned the key of the outer door. What followed seemed to
happen as though by some mysteriously directed force. The figures of men
came stealing out from the hidden places. The clerk who had been working
so hard at his desk calmly divested himself of a false mustache and
wig, and, assuming a more familiar appearance, strolled out into
the warehouse. De Grost looked around him with absolutely unruffled

perhaps, but my supers are not to be taken seriously. Since you are
here, Baron, might I ask you to precede me a few steps to the tasting
office?

"By all means," De Grost answered cheerfully. "It is this way, I
believe."

He walked with unconcerned footsteps down the warehouse, on either side
of which were great bins and a wilderness of racking, until he came to
a small, glass-enclosed office, built out from the wall. Without
hesitation he entered it, and removing his hat, selected the more
comfortable of the two chairs. Bernadine alone of the others followed
him inside, closing the door behind. De Grost, who appeared exceedingly
comfortable, stretched out his hand and took a small black bottle from a
tiny mahogany racking fixed against the wall by his side.

"You will excuse me, my dear Bernadine,
