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. One evening he returned home from the office to Maud, overflowing with a new and most important discovery. 'Well, the thing's all but proved, at last!' he cried in a triumphant voice, as he kissed her warmly; 'at least, that is to say, I've found a valuable clue that will decide the matter finally one way or the other. I've discovered a conveyance of the sixteenth century, dated 1533--here's a verbatim copy of it--which describes Thomas Plantagenet, our great-great-grandfather's grandfather, as being really the son of Giles Plantagenet, the missing-link man, who is said in it to have owned a house--and this, you will see, is the new and important point--at Framlingham, in Suffolk. He seems to have been some sort of a petty tradesman.
