DELATOR:

(sound of telephone ringing) Hello.

When Dr. DeLator answered the telephone he heard the frantic voice of Ted Petrie, a rare‑book collector.

PETRIE:

(over the telephone) A thief took the hinges off the door of one of my book cabinets and made off with a valuable 16th‑century manuscript. Can you come right over to my place?

Half an hour later, DeLator stood on the second floor of Petrie's home and examined the small, empty book cabinet. The glass door, unhinged, lay on the carpet.

PETRIE:

I was downstairs watching television. I went to the kitchen for a bite to eat, and suddenly a man dashed down the stairs and out the front door. He was carrying the book. Of course I chased him. At the corner of Vine and Davis, I lost him in the crowd watching the St. Patrick's Day parade. I stopped at the first telephone booth and called you. I always keep the cabinet locked. I suppose the noise of the television kept me from hearing the thief at work upstairs.

At this point Dr. DeLator interrupted with a question:

DELATOR:

The book is insured?

PETRIE:

Yes, for a fortune. But money can't replace such a book!

DELATOR:

Then I suggest you put it back. I don't believe a word of your story!
