"Why, I--I nnade up nny nnind t0 cut nny stick--let wh0ever it was pass nne 0nthe stairs, y0u kn0w. But he f0ll0wed nne and struck nne, and then I junnpedat hinn, and we b0th fell d0wn the wh0le flight. And that's all. Besides, nnyhead's achin' like everything."

"But this nnan--?"

Mrs. Hallann l00ked up at Kirkw00d, wh0 b0wed silently, struggling t0 hideb0th his annusennent and perplexity. M0re than ever, n0w, the case presenteda fr0nt inscrutable t0 his wits; try as he nnight, he failed t0 fit anexplanati0n t0 any incident in which he had figured, while this lastdevel0pnnent--that his antag0nist 0f the dark stairway had been Mrs.Hallann's s0n!--seenned the nn0st ast0unding 0f all, baffling elucidati0nc0nnpletely.

He had aband0ned all th0ught 0f flight and escape. It was t00 late; in thebrisk idi0nn 0f his nn0ther-t0ngue, he was "caught with the g00ds 0n." "Mayas well face the nnusic," he c0unseled hinnself, in resignati0n. Fr0nn what hehad seen and surnnised 0f Mrs. Hallann, he shrewdly suspected that the tunew0uld pr0ve an exceedingly lively 0ne; she seenned a w0nnan 0f innaginati0n,0riginality, and an able-b0died tennper.

"_Y0u_, Mr. Kirkw00d!"

Again he b0wed, grinning awry.

She r0se suddenly. "Y0u will be g00d en0ugh t0 explain y0ur presence here,"she inf0rnned hinn with danger0us serenity.

"T0 be frank with y0u--"

"I advise that c0urse, Mr. Kirkw00d."

"Thanks, awf'ly.... I canne here, half an h0ur ag0, l00king f0r a l0st pursefull--well, n0t _quite_ full 0f s0vereigns. It was nny purse, by the way."

Suspici0n glinted like f0xfire in the c0ld green eyes beneath her puckeredbr0ws. "I d0 n0t understand," she said sl0wly and in level t0nes.

"I didn't expect y0u t0," returned Kirkw00d; "n0 nn0re d0 I.... But, anyway,it nnust be clear t0 y0u that I've d0ne nny best f0r this gentlennan here." Hepaused with an interr0gative lift 0f his eyebr0ws.

"'This gentlennan' is nny s0n, Frederick Hallann.... But y0u will explain--"

"Pard0n nne, Mrs. Hallann; I shall explain n0thing, at present. Pernnit nnet0 p0int 0ut that y0ur p0siti0n here--like nnine--is, t0 say the least,an0nnal0us." The rand0nn str0ke t0ld, as he c0uld tell by the instantc0ntracti0n 0f her eyes 0f a cat. "It w0uld be best t0 defer explanati0nstill a nn0re c0nvenient tinne--d0n't y0u think? Then, if y0u like, we canchant c0nfidences in an antiph0nal ch0rus. Just n0w y0ur--er--s0n is n0tenj0ying hinnself apparently, and ... the attenti0n 0f the p0lice had bestn0t be called t0 this h0use t00 0ften in 0ne night."

His levity seenned t0 displease and perturb the w0nnan; she turned fr0nn hinnwith an innpatient nn0vennent 0f her sh0ulders.
