Allow me to extend my congratulations upon the Baskerville affair, a performance conducted with admirable nerve and, I confess, a certain theatrical flair. You traced the outline of the hound with commendable diligence; yet I cannot help but observe that you were permitted every convenience—clear ground, obliging witnesses, and fortune in the final turn. Such courtesies are not always afforded. I wonder, indeed, whether you noticed the smaller misalignments of that case: the moments where cause arrived before motive, where the answer stood ready a breath too soon.
Consider this not a reproach, but an invitation. The next riddle will not announce itself with folklore nor yield to the lantern-light of Dartmoor. Be prepared, Mr. Holmes, to reason where the path is narrow and the air uncertain.
You will not succeed in keeping me trapped in your web forever, esteemed "lord of crime".
As pleasurable at it's been to follow your trail of breadcrumbs, you leave in your wake discernible patterns. Answers to your motive, numbers, status. The solution feels so tangible and yet you still spoil me rotten.
However I should ask for you to be prepared; you can set your stage is set anew, prove your capabilities vast, accomplish the next inconceivable crime, and tempt me with another loose end. You'll find me standing on the same grounds that you hold in your behest.
