When he talked like that, Maud thought it was really beautiful. She wondered how Mary could ever be insensible to the romantic charms of such old descent. But there! Mary wasn't a Plantagenet--only a mere Welsh Tudor; and though she was a dear good girl, and as sweet as they're made, how could you expect her to enter fully into the feelings of the real old family? As for Archie Gillespie, he said to Mary more than once:
'Let Dick go his own way, Miss Tudor; it gives him pleasure. He thinks some mysterious good is going to come out of it all for him and his, if he can fill in the missing links in the Plantagenet pedigree. Of course, that's pure moonshine. Still, we must always remember it was the Plantagonet pedigree that gave our Dick his first interest in English history, and so made him what he is; and anything deserves respect which could keep Edmund Plantagenet's children from degenerating, as they would have degenerated, from their father's example, without this inspiriting idea of _noblesse oblige_: an idea which has made Dick and Maud--I mean, Miss Plantagenet--hold their heads high through life in spite of their poverty. It can do Dick no harm now to pursue a little farther this innocent hobby; it will give him a better insight into the by-ways and alleys of early English history; and if he can really establish the Plantagenet pedigree throughout, it may serve to call attention to him as a sound historical researcher. Fortunately, he knows what evidence is; and he won't go wrong, therefore, by making heedless assumptions and incredible skips and jumps, like half our genealogists.'
So Dick persevered for fully twelve months in his eager attempt, by hook and by crook, to trace his own family up to Lionel of Clarence, upon whom Mr. Plantagenet himself had early fixed--at pure haphazard--as the special transmitter of the Plantagenet blood to the later branches of the House, himself included. The longer Dick worked at it, too, the more confident he became of ultimate success. Step by step turned out right. He had brought the thing down, he told Mary, to a moral certainty; only one link now remained to complete the entire pedigree. That's always the way, it may be mentioned parenthetically, with your doubtful genealogy; there's only one link missing--but, unfortunately, that's the link on proof of which the whole chain is dependent. And very naturally, too: for this is how the thing works out. You track your own genealogy, let us say, back to a person named Plantagenet, who lived some time in the sixteenth century, and with whom you are really and undoubtedly connected by an unbroken and traceable ancestral series. Then you track the family tree of Lionel of Clarence forward, in the opposite direction, to a real and historical Plantagenet who 'flourished,' as the books say, near the end of the fifteenth century. After that you say: 'If my ancestor, the sixteenth-century Plantagenet, turns out to be the son of Lionel's descendant in the fifteenth century--as is extremely probable--why, then, it's all made out--I'm descended direct from Lionel of Clarence; and in any case, don't you see, there's only one link missing!' Wise genealogists usually abstain on purpose from the attempt to hunt up that fatal missing link; they know right well that the safest plan is to assume identity, while efforts at proving it are frequently disastrous. But Dick was still young, and not perhaps overwise; so once he had brought down the matter to a question of a solitary missing link, he couldn't rest night or day till he had finally settled it.
