my dear Watson, there we come into those realms of conjecture, where the most logical mind may be at fault.

But it is evident to me that the logical way to approach the case is to begin by trying to throw some light upon the first incident—the curious will, so suddenly made, and to so unexpected an heir.

I had the good fortune to seize upon that, and everything which has occurred since then has served to confirm my original supposition, and, indeed, was the logical sequence of it.
