But I was not in this instance to be wheedled by my aunt. I wrote in return, saying how much I was amazed at my grandmother telling such fibs, and proved to her most satisfactorily that I was in London at the time they supposed I might have been at Chatham. That my aunt had been requested by my mother to try to find out the truth, I was well convinced: but I felt my secret of too much importance to trust either of them and from that time the subject was never mentioned; and I believe it was at last surmised that the letter might have been destroyed accidentally or purposely by the maid-servant, and that my grandmother had been frightened at nothing at all--an opinion more supported, as the maid, who had taken advantage of my mother's retiring to her room, and had been out gossiping, declared that she had not left the premises three minutes, and not a soul could have come in. Moreover, it was so unlikely that I could have been in Chatham without being recognised by somebody. My grandmother shook her head, and said nothing during all this canvassing of the question; but my aunt Milly declared that I never would have been at Chatham without coming to see her. And it was her opinion that the servant girl had read the letter when left on the table, and had taken it out to show to her associates; and somebody who wished to have a hold upon my mother by the possession of the letter had retained it. I think my mother came to that opinion at last, and it was the source of much uneasiness to her. She dared not say a word to Captain Delmar, and every day expected to have an offer made of returning the letter, upon a certain sum being paid down. But the offer was never made, as the letter had been sewed up by Bob Cross in the piece of seal-skin, and was worn round my neck with a ribbon, with as much care as if it had been a supposed bit of the wood of the true cross, possessed by some old female Catholic devotee. But long before all these discussions were over, H.M. ship Calliope had been ordered to sail, and was steering down the Channel before a smart breeze. CHAPTER EIGHTEEN. Although I have so much to say as to oblige me to pass over without notice the majority of my companions, I think I ought to dedicate one chapter to a more particular description of those with whom I was now principally in contact on board of the Calliope. I have already spoken much of the Honourable Captain Delmar, but I must describe him more particularly. When young, he must have been a very handsome man; even now, although nearly fifty years of age, and his hair and whiskers a little mixed with grey, he was a fine-looking personage, of florid complexion, large blue eyes, nose and mouth very perfect: in height he was full six feet; and he walked so erect that he looked even taller.
