The remarkable mystery, surrounding as it did one of the best-known
scientists in the land, had already gripped my senses. Therefore I did

cars at the portico of that house of tragedy.
A white-faced, grave-eyed man in black, the man Antonio, opened the door

only pulled my companion forward into the dining-room on the left, and
with his thin, bony finger pointed within.
