'Indeed?' said Logan. 'Yes. I would not speak of it to everybody; in fact, I have spoken of it to no one; but recently, examining some documents in my muniment-room, I made a discovery as interesting to me as it must be to you. Our ancestors three hundred years ago--in 1600, to be exact--were fellow conspirators.' 'Ah, the old Gowrie game, to capture the King?' asked Logan, who had once kidnapped a cat. His knowledge of history was mainly confined to that obscure and unexplained affair, in which his wicked old ancestor is thought to have had a hand. 'That is it,' said the visitor--'the Gowrie mystery! You may remember that an unknown person, a friend of your ancestor, was engaged?' 'Yes,' said Logan; 'he was never identified. Was his name Harris?' The peer half rose to his feet, flushed a fine purple, twiddled the obsolete little grey tuft on his chin, and sat down again. 'I think I said, Mr. Logan, that the hitherto unidentified associate of your ancestor was _a member of my own family_. Our name is _not_ Harris--a name very honourably borne--our family name is Guevara. My ancestor was a cousin of the brave Lord Willoughby.' 'Most interesting! You must pardon me, but as nobody ever knew what you have just found out, you will excuse my ignorance,' said Logan, who, to be sure, had never heard of the brave Lord Willoughby. 'It is I who ought to apologise,' said the visitor. 'Your mention of the name of Harris appeared to me to indicate a frivolity as to matters of the past which, I must confess, is apt to make me occasionally forget myself. _Noblesse oblige_, you know: we respect ourselves--in our progenitors.' 'Unless he wants to prevent someone from marrying his great-grandmother, I wonder what he is doing with his Tales of a Grandfather _here_,' thought Logan, but he only smiled, and said, 'Assuredly--my own opinion. I wish I could respect _my_ ancestor!' 'The gentleman of whom I speak, the associate of your own distant progenitor, was the founder of our house, as far as mere titles are concerned. We were but squires of Northumbria, of ancient Celtic descent, before the time of Queen Elizabeth. My ancestor at that time--' 'Oh bother his pedigree!' thought Logan. '--was a young officer in the English garrison of Berwick, and _he_, I find, was _your_ ancestor's unknown correspondent. I am not skilled in reading old hands, and I am anxious to secure a trustworthy person--really trustworthy--to transcribe the manuscripts which contain these exciting details.' Logan thought that the office of the Disentanglers was hardly the place to come to in search of an historical copyist. However, he remembered Miss Willoughby, and said that he knew a lady of great skill and industry, of good family too, upon whom his client might entirely depend. 'She is a Miss Willoughby,' he added.
