Heaven created an immutable pattern for ten thousand ages, Regulating sun and stars above, mountains and rivers below; Thereafter the sages of old did model our sacred social order, Taking Heavenly Justice as warp, and man-made Law as woof.

A wise and honest judge is Heaven's unerring instrument, The people's father and mother, both compassionate and stern; In his court the oppressed obtain redress of all their wrongs, Nocriminal there escapes, despite base fraud and guile.

Under the present illustrious Ming dynasty, in the Yoong-lo era, our Empire is at peace, crops are plentiful, there are neither droughts nor floods, and the people are prosperous and content. This fortunate state of affairs is due entirely to the August Virtue of His Imperial Majesty. Naturally in this blessed time of peace crimes are few, so that the present provides scant material for the study of crime and detection. Rather than the present one must turn to the past for accounts of baffling crimes, and their marvellous solution by perspicacious magistrates.
