"There is certainly something wrong, somewhere," remarked Petherton, after a time. "However, we are in a position to begin a systematic inquiry. Here," he went on, drawing a paper from his desk, "is a cablegram which arrived first thing this morning from New York--from an agent who has been making a search for me in the shipping lists. This is what he says: 'Marston Greyle, St. Louis, Missouri, booked first-class passenger from New York to Falmouth, England, by S.S. _Araconda_, September 28th, 1912.' There--that's something definite. And the next thing," concluded the old lawyer, with a shrewd glance at Sir Cresswell, "is to find out if the Marston Greyle who landed at Falmouth is the same man whom we have recently seen!" CHAPTER XVI IN TOUCH WITH THE MISSING Sir Cresswell Oliver took the cablegram from Petherton and read it over slowly, muttering the precise and plain wording to himself. "Don't you think, Petherton, that we had better get a clear notion of our exact bearings?" he said as he laid it back on the solicitor's desk. "Seems to me that the time's come when we ought to know exactly where we are. As I understand it, the case is this--rightly or wrongly we suspect the present holder of the Scarhaven estates. We suspect that he is not the rightful owner--that, in short, he is no more the real Marston Greyle than you are. We think that he's an impostor--posing as Marston Greyle. Other people--Mrs. Valentine Greyle, for example--evidently think so, too. Am I right?" "Quite!" responded Petherton. "That's our position--exactly." "Then--in that case, what I want to get at is this," continued Sir Cresswell. "How does this relate to my brother's death? What's the connection? That--to me at any rate--is the first thing of importance. Of course I have a theory. This, that the impostor did see my brother last Sunday afternoon. That he knew that my brother would at once know that he, the impostor, was not the real Marston Greyle, and that the discovery would lead to detection. And therefore he put him out of the way. He might accompany him to the top of the tower and fling him down. It's possible. Do you follow me?"
