"Ah, yes--the magazines! Yes, yes, indeed! publicity is unavoidable, unavoidable, Mr.Cleggett! But this box, now----" The great detective interrupted himself to laugh again, a trifle complacently, Cleggett thought.
"I will not mystify you, Mr.Cleggett, about the box.

Mystification is one of the tricks of the older schools of detection.

I never practice it, Mr.Cleggett.

With me, the detection of crime is a business--yes, a business.

I will tell you presently how the box came into my possession." "It IS in your possession ?" Cleggett felt a dull pang of the heart.
If the box of Reginal Maltravers were in the hands of Logan Black he could at least trade the other oblong box to Loge for it, and thus save Lady Agatha.
