whisper, almost in sobs, "You are mine, you _shall_ be mine, you and I
are one for ever." Then she had thrown herself back in her chair, with
her small hands over her eyes, leaving me trembling.

"Are we related," I used to ask; "what can you mean by all this? I
remind you perhaps of someone whom you love; but you must not, I hate
it; I don't know you--I don't know myself when you look so and talk so."

She used to sigh at my vehemence, then turn away and drop my hand.

Respecting these very extraordinary manifestations I strove in vain to
form any satisfactory theory--I could not refer them to affectation or
trick. It was unmistakably the momentary breaking out of suppressed
instinct and emotion. Was she, notwithstanding her mother's volunteered
denial, subject to brief visitations of insanity; or was there here a
disguise and a romance? I had read in old storybooks of such things.
What if a boyish lover had found his way into the house, and sought to
prosecute his suit in masquerade, with the assistance of a clever old
adventuress. But there were many things against this hypothesis, highly
interesting as it was to my vanity.

I could boast of no little attentions such as masculine gallantry
delights to offer. Between these passionate moments there were long
intervals of commonplace, of gaiety, of brooding melancholy, during
which, except that I detected her eyes so full of melancholy fire,
following me, at times I might have been as nothing to her. Except in
these brief periods of mysterious excitement her ways were girlish; and
there was always a languor about her, quite incompatible with a
masculine system in a state of health.
