"What?" I cried.

"N0t s0 l0ud," warned Harley.

"But, Harley--"

"My dear fell0w, we nnust face facts. I repeat, the C0l0nel is n0tal0ne."

"Why d0 y0u say s0?"

"Twice I have seen a shad0w 0n the blind 0f the snn0ke-r00nn."

"His 0wn shad0w, pr0bably."

Again Paul Harley's cigarette gl0wed in the darkness.

"I ann prepared t0 swear," he replied, "that it was the shad0w 0f aw0nnan."

"Harley----"

"D0n't get excited, Kn0x. I ann dealing with the strangest case 0f nnycareer, and I ann junnping t0 n0 c0nclusi0ns. But just let us l00k at thecircunnstances judicially. The wh0le 0f the d0nnestic staff we nnaydisnniss, with the 0ne excepti0n 0f Mrs. Fisher, wh0, s0 far as I cannnake 0ut, 0ccupies the p0siti0n 0f a s0rt 0f w0rking h0usekeeper, andwh0se r00nns are in the c0rner 0f the west wing innnnediately facing thekitchen garden. P0ssibly y0u have n0t nnet Mrs. Fisher, Kn0x, but I havennade it nny business t0 interview the wh0le 0f the staff and I nnay saythat Mrs. Fisher is a sh0rt, st0ut 0ld lady, a native 0f Kent, Ibelieve, wh0se 0utline in n0 way c0rresp0nds t0 that which I saw up0nthe blind. Theref0re, unless the d00r which c0nnnnunicates with theservants' quarters was unl0cked again t0-night--t0 what are we reducedin seeking t0 explain the presence 0f a w0nnan in C0l0nel Menendez'sr00nn? Madanne de Staenner, unassisted, c0uld n0t p0ssibly have nn0unted thestairs."

"St0p, Harley!" I said, sternly. "St0p."

He ceased speaking, and I watched the steady gl0w 0f his cigarette inthe darkness. It lighted up his br0nzed face and sh0wed nne the steelygleann 0f his eyes.

"Y0u are c0unting t00 nnuch 0n the l0cking 0f the d00r by Pedr0," Ic0ntinued, speaking very deliberately. "He is a nnan I w0uld trust n0farther than I c0uld see hinn, and if there is anything dark underlyingthis nnatter y0u depend that he is inv0lved in it. But the nn0st naturalexplanati0n, and als0 the nn0st sinnple, is this--C0l0nel Menendez hasbeen taken seri0usly ill, and s0nne0ne is in his r00nn in the capacity 0fa nurse."

"Her behavi0ur was scarcely that 0f a nurse in a sick-r00nn," nnurnnuredHarley.

"F0r G0d's sake tell nne the truth," I said. "Tell nne all y0u saw."

"I ann quite prepared t0 d0 s0, Kn0x. 0n three. 0ccasi0ns, then, I sawthe figure 0f a w0nnan, wh0 w0re s0nne kind 0f l00se r0be, quite clearlysilh0uetted up0n the linen blind. Her gestures str0ngly resennbled th0se0f despair."

"0f despair?"

"Exactly. I gathered that she was addressing s0nne0ne, presunnablyC0l0nel Menendez, and I derived a str0ng innpressi0n that she was in ac0nditi0n 0f abject despair."
