Miss Raven, timid, and a little shy of concentrated attention, laid the photograph again on the table. "Don't--don't you think there may be some explanation of this in what Salter Quick said to Mr. Middlebrook when they met on the cliffs?" she asked. "He told Mr. Middlebrook that he wanted to find a churchyard where there were graves of people named Netherfield, but he didn't know exactly where it was, though it was somewhere in this locality. Now supposing this is a rough outline of that churchyard? These outer lines may be the wall--then these little marks may show the situation of the Netherfield graves. And that cross in the corner--perhaps there is something buried, hidden, there, which Salter Quick wanted to find?" The detective uttered a sharp exclamation and snatched up the photograph again. "Good! Good!" he said. "Upon my word, I shouldn't wonder! To be sure, that may be it. What's against it?" "This," remarked Mr. Cazalette solemnly. "That there isn't anybody of the name of Netherfield buried between Alnmouth and Budle Bay! That's a fact." "Established," added the police-inspector, "by as an exhaustive inquiry as anybody could make. It is a fact--as Mr. Cazalette says." "Well," observed Scarterfield, "but Salter Quick may have been wrong in his locality. You can be sure of this--whatever secret he held was got from somebody else. He may have been twenty, thirty, even fifty miles out. But we know something--the Netherfield who was with him on the _Elizabeth Robinson_ hailed from Blyth, in this county. I'm going to Blyth myself--tomorrow; I'll find out if there are Netherfields buried about there. Personally, I believe Miss Raven's hit the nail on the head--this is a rough chart of a spot Salter Quick wanted to find--where, no doubt, something is hidden. What? Who knows? But--judging from the fact that two men have been murdered for the secret of it--something of great value. Buried treasure, no doubt." "That's precisely what I've been thinking from the very first," murmured Mr. Cazalette. "And ye'll have to go back--to go back, my man!" "It's certainly the only way of going forward," agreed Scarterfield with a laugh. "But now, before we part, gentlemen, let us see where we've got to. I, for myself, have drawn five distinct conclusions about this affair: "_First_--That the Quicks, Noah and Salter, were in possession of a secret, which was probably connected with their shipmate of the _Elizabeth Robinson_, Netherfield, who hailed from Blyth; "_Second_--That certain men knew the Quicks to be in possession of that secret and murdered both to get hold of it; "_Third_--That they failed to get it from either Noah or Salter; "_Fourth_--That Mr. Cazalette's zeal about the tobacco-box, publicly expressed, put the criminals on a new scent, and that they, in pursuance of it, stole both the tobacco-box and Mr. Cazalette's pocket-book;
