The Valley of Fear

\"It is Porlock\'s writing,\" said he thoughtfully. \"I can hardly doubt that it is Porlock\'s writing, though I have seen it only twice before.


The Greek e with the peculiar top flourish is distinctive. But if it is Porlock, then it must be something of the very first importance.\"


He was speaking to himself rather than to me; but my vexation disappeared in the interest which the words awakened.


\"Who then is Porlock?\" I asked.

\"Porlock, Watson, is a nom-de-plume, a mere identification mark; but behind it lies a shifty and evasive personality. In a former letter he frankly informed me that the name was not his own, and defied me ever to trace him among the teeming millions of this great city. Porlock is important, not for himself, but for the great man with whom he is in touch. Picture to yourself the pilot fish with the shark, the jackal with the lion?anything that is insignificant in companionship with what is formidable: not only formidable, Watson, but sinister?in the highest degree sinister. That is where he comes within my purview. You have heard me speak of

Professor Moriarty?\"
