hoops of diamonds and emeralds used as ear-rings; a sparkling clasp which caught at her white throat the wrap which she had thrown about her ball gown—­for now I saw she was in full evening dress.  I guessed she had been an attendant at the great ball, that ball which I had missed with so keen a regret myself—­the ball where I had hoped to dance with Elisabeth.  Without doubt she had lost her way and was asking the first stranger for instructions to her driver.

My lady, whoever she was, seemed pleased with her rapid temporary scrutiny.  With a faint murmur, whether of invitation or not I scarce could tell, she drew back again to the farther side of the seat.  Before I knew how or why, I was at her side.  The driver pushed shut the door, and whipped up his team.

Personally I am gifted with but small imagination.  In a very matter of fact way I had got into this carriage with a strange lady.  Now in a sober and matter of fact way it appeared to me my duty to find out the reason for this singular situation.

“Madam,” I remarked to my companion, “in what manner can I be of service to you this evening?”

I made no attempt to explain who I was, or to ask who or what she herself was, for I had no doubt that our interview soon would be terminated.

“I am fortunate that you are a gentleman,” she said, in a low and soft voice, quite distinct, quite musical in quality, and marked with just the faintest trace of some foreign accent, although her English was perfect.

I looked again at her.  Yes, her hair was dark; that was sure.  It swept up in a great roll above her oval brow.  Her eyes, too, must be dark, I confirmed.  Yes—­as a passed lamp gave me aid—­there were strong dark brows above them.  Her nose, too, was patrician; her chin curving just strongly enough, but not too full, and faintly cleft, a sign of power, they say.

A third gracious lamp gave me a glimpse of her figure, huddled back among her draperies, and I guessed her to be about of medium height.  A fourth lamp showed me her hands, small, firm, white; also I could catch a glimpse of her arm, as it lay outstretched, her fingers clasping a fan.  So I knew her arms were round and taper, hence all her limbs and figure finely molded, because nature does not do such things by halves, and makes no bungles in her symmetry of contour when she plans a noble specimen of humanity.  Here was a noble specimen of what woman may be.

On the whole, as I must confess, I sighed rather comfortably at the fifth street lamp; for, if my chief must intrust to me adventures of a dark night—­adventures leading to closed carriages and strange companions—­I had far liefer it should be some such woman as this.  I was not in such a hurry to ask again how I might be of service.  In fact, being somewhat surprised and somewhat pleased, I remained silent now for a time, and let matters adjust themselves; which is not a bad course for any one similarly engaged.
