But wait, perhaps I begin to understand--the lieutenant who brought me here; his voice has been echoing in my ears all night in familiarity.

He is some near relative of yours--this Eric ?" "Oh, you have overheard?
You know the name through hearing Captain Grant speak ?" "Yes; I could not very well help doing so.

Peter had stationed me in the library, but there was nothing said between you two to make me suspect your identity." "You supposed me to be the lieutenant ?" "You have not suspected ?" she asked.

"You did not know this was my home ?" "Why should I not?
The voice was the same; at least sufficiently similar to deceive me, and he never addressed you in a way to arouse my suspicions.

Is your brother named Eric ?" "Yes; I told you, did I not, that we are twins?
The physical resemblance between us is very strong; no doubt our voices sound alike also, or would to a comparative stranger.
