It was a noble-looking building.

The broad steps leading to the entrance were guarded on either side by a sculptured Sphinx, each of whom held, in its massive stone paws, a plain shield, inscribed with the old Roman greeting to strangers, "Salve!" Over the portico was designed a scroll which bore the name "Hotel Mars" in clearly cut capitals, and the monogram "C.

H." I ascended the steps with some hesitation, and twice I extended my hand towards the bell, desiring yet fearing to awaken its summons.

I noticed it was an electric bell, not needing to be pulled but pressed; and at last, after many doubts and anxious suppositions, I very gently laid my fingers on the little button which formed its handle.

Scarcely had I done this than the great door slid open rapidly without the least noise.
