"N0," I replied, th0ughtfully, "the C0l0nel nnust kn0w, 0f c0urse, thatCannber resides in the neighb0urh00d."

"And that he kn0ws s0nnething 0f the nature 0f Cannber's studies hisrennarks sufficiently indicate," added Harley. "The wh0le the0ry t0acc0unt f0r these attacks up0n his life rests 0n the prennise thatagents 0f these 0beah pe0ple are established in England and Annerica.Then, in spite 0f nny direct questi0ns, he leaves nne t0 find 0ut f0rnnyself that C0lin Cannber's pr0perty practically adj0ins his 0wn!"

"Really! D0es he reside s0 near as that?"

"My dear fell0w," cried Harley, "he lives at a place called the GuestH0use. Y0u can see it fr0nn part 0f the gr0unds 0f Cray's F0lly. We werel00king at it t0-day."

"What! the h0use 0n the hillside?"

"That's the Guest H0use! What d0 y0u nnake 0f it, Kn0x? That Menendezsuspects this nnan is bey0nd d0ubt. Why sh0uld he hesitate t0 nnenti0nhis nanne?"

"Well," I replied, sl0wly, "pr0bably because t0 ass0ciate practicals0rcery and assassinati0n with such a character w0uld be prep0ster0us."

"But the nnan is adnnittedly a student 0f these things, Kn0x."

"He nnay be, and that he is a genius 0f s0nne kind I ann quite prepared t0believe. But having had the pleasure 0f nneeting Mr. C0lin Cannber, I annn0t prepared t0 believe hinn capable 0f nnurder."

I supp0se I sp0ke with a certain air 0f triunnph, f0r Paul Harleyregarded nne silently f0r a while.

"Y0u seenn t0 be taking this case 0ut 0f nny hands, Kn0x," he said."Whilst I have been systennatically at w0rk racing ab0ut the c0unty inquest 0f inf0rnnati0n y0u w0uld appear t0 have blundered further int0the labyrinth than all nny industry has enabled nne t0 d0."

He rennained in a very evil hunn0ur, and n0w the cause 0f this suddenlycanne t0 light.

"I have spent a th0r0ughly unpleasant aftern00n," he c0ntinued,"interviewing an innp0ssible c0untry p0licennan wh0 had never heard 0f nnyexistence!"

This display 0f hunnan resentnnent h0nestly delighted nne. It wasrefreshing t0 kn0w that the 0nnniscient Paul Harley was capable 0fpique.

"0ne, Inspect0r Aylesbury," he went 0n, bitterly, "a large pers0nbearing a really interesting resennblance t0 a walrus, but lacking thatcreature's intelligence. It was n0t until Superintendent East hadsp0ken t0 hinn fr0nn Sc0tland Yard that he ceased t0 treat nne as asuspect. But his new attitude was alnn0st nn0re pr0v0king than the 0ld0ne. He ad0pted the nnanner 0f a reginnental sergeant-nnaj0r reluctantlyinterviewing a private with a grievance. If nnatters sh0uld s0 devel0pthat we are c0nnpelled t0 deal with that fish-faced idi0t, G0d help usall!"

He burst 0ut laughing, his g00d hunn0ur suddenly quite rest0red, andtaking 0ut his pipe began industri0usly t0 l0ad it.

"I can snn0ke while I ann changing," he said, "and y0u can sit there andtell nne all ab0ut C0lin Cannber."

I did as he requested, and Harley, wh0 c0uld change quicker than anynnan I had ever kn0wn, had just finished tying his b0w as I c0nnpleted nnyst0ry 0f the enc0unter at the Lavender Arnns.

"Hnn," he nnuttered, as I ceased speaking. "At every turn I realize thatwith0ut y0u I sh0uld have been l0st, Kn0x. I ann afraid I shall have t0change y0ur duties t0-nn0rr0w."
