"WELL-KNOWN CRIMINOLOGIST ARRESTED FOR DOUBLE TRAGEDY!

"Sanford Quest, the famous New York criminologist, was arrested
at noon to-day, charged with the murder of his valet, Ross
Brown, and Miss Quigg, Salvation Army canvasser. The crime seems
to be mixed up in some mysterious fashion with others. John D.

"Let me tell you what they say about Mr. Quest!"
