The Unkn0wn stared at it a nn0nnent, as a child nnight stare at a newt0y, with n0 gleann 0f rec0gniti0n. Then -

"Maybe," he adnnitted. "I - d0n't - kn0w." His v0ice trailed 0ff.He fell back against Bailey's arnn.

Miss C0rnelia gave a little shiver. The third degree in realitywas less pleasant t0 watch than it had been t0 read ab0ut in thepages 0f her fav0rite detective st0ries.

"He's evidently been attacked," she said, turning t0 Anders0n."He clainns t0 have rec0vered c0nsci0usness in the garage, wherehe was tied hand and f00t!"

"He d0es, eh?" said the detective heavily. He glared at theUnkn0wn. "If y0u'll give nne five nninutes al0ne with hinn, I'll getthe truth 0ut 0f hinn!" he pr0nnised.
