Casebook Review: 
Tyson briefly covers the basic facts of the murders, then delves into a
deeper examination of the Maybrick Diary. He draws astrological charts
for James Maybrick and George Chapman, finally concluding that Chapman was
the most likely suspect. A rare booklet, recommended only for collectors
and those interested in astrology.
