"Covering his face?"
"So as to cover his face completely. I was staring at him in wonder, when the boy, seeming to divine the other's approach, whispered, 'Turn your head away! Turn your head away!"
"He was referring to the man with the veil?"
"Undoubtedly. Of course I did nothing of the kind, but it was impossible to discern the stranger's features through the thick gauze, although he passed quite close to me. He had not proceeded another three paces, I should think, before my boy had snatched up the shafts and darted across the bridge as though all hell were after him! Here's the odd thing, though; I could never induce him to speak a word on the subject afterwards! I bullied him and bribed him, but all to no purpose. And although I must have asked more than a hundred Chinamen in every station of society from mandarin to mendicant, 'Who or what is The Scorpion?' one and all looked stupid, blandly assuring me that they did not know what I meant."
"H'm!" said Dunbar, "it's a queer yarn, certainly. How long ago would that be, doctor?"
"Roughly—five years."
"It sounds as though it might belong to the case. Some months back, early in the winter, we received instructions at the Yard to look out everywhere in the press, in buffets, theatres, but particularly in criminal quarters, for any reference (of any kind whatever) to a scorpion. I was so puzzled that I saw the Commissioner about it, and he could tell me next to nothing. He said the word had come through from Paris, but that Paris seemed to know no more about it than we did. It was associated in some way with the sudden deaths of several notable public men about that time; but as there was no evidence of foul play in any of the cases, I couldn't see what it meant at all. Then, six weeks ago, Sir Frank Narcombe, the surgeon, fell dead in the foyer of a West-End theatre—you remember?"
