It has long been a source of wonder to me why the leading criminological writers--men like Edmund Lester Pearson, H. B. Irving, Filson Young, Canon Brookes, William Bolitho, and Harold Eaton--have not devoted more space to the Greene tragedy; for here, surely, is one of the outstanding murder mysteries of modern times--a case practically unique in the annals of latter-day crime.

A detective novel should contain no long descriptive passages, no literary dallying with side-issues, no subtly worked-out character analyses, no 'atmospheric' preoccupations. Such matters have no vital place in a record of crime and deduction. They hold up the action and introduce issues irrelevant to the main purpose, which is to state a problem, analyze it, and bring it to a successful conclusion. To be sure, there must be a sufficient descriptiveness and character delineation to give the novel verisimilitude.

Of all the criminal cases in which Philo Vance participated as unofficial investigator, the most sinister, the most bizarre, the seemingly most incomprehensible, and certainly the most terrifying was the one that followed the famous Greene murders.
