IN BRIEF: Who Killed Oliver Cromwell? - Leonard R. Gribble

 I've not read any of the Detective Inspector Anthony Slade mystery novels I've owned over the years until a few days ago.  If Who Killed Oliver Cromwell? (1938) is any indication of Gribble's style he seems to have been inspired by Edgar Wallace. While the title and premise succeeded in luring me into purchasing this copy, the story ended up very familiar.

Slade works for Department X2, some specialized section of Scotland Yard that is never really explained.  Maybe it's not even part of Scotland Yard.  I never understood the designation or what exactly they specialize in or why they get called upon.  In any case, he shows up at the scene of a murder at a masquerade party (or fancy dress ball as they call them in British GAD novels).  A well known financier named Stephen Ironsides comes dressed as his historical hero, Oliver Cromwell and someone stabbed him then made off with the weapon. The knife was stolen from another attendee, Peter Storand, who was dressed as a Roundhead. In fact, several people came dressed as historical figures associated with Cromwell and the Commonwealth of England era.  Sir Henry Dillocks at the suggestion of his daughter Frances comes as Charles I and she came as Henrietta Marie, his consort. This costumed trivia is an ironic overlay to the relationships of the primary characters: the murder victim was planning to marry Frances; Peter is in love with Frances and trying to dissuade her from agreeing to the marriage her father wants with Ironsides.

The story begins as a detective novel with the above eccentric plot details then, when it is discovered that the murder victim is an impostor, the book slowly morphs into an Edgar Wallace style thriller. As more suspects are found a subplot with gun runners, petty criminals and Ironsides' failing businesses complicate the plot.  It all starts to fall apart when Frances is kidnapped followed swiftly by the introduction of doppelgängers, plastic surgery, bribed servants, and ending with a forced marriage at sea performed by the ship's captain with the police in hot pursuit to stop it. Immediately, I thought of The Avenging Saint by Leslie Charteris, written several years before Gribble's book, which has exactly the same action-filled climax in the finale. While there are some unexpected incidents, much of Who Killed Oliver Cromwell? is laden with heavy melodrama and tiresome heightened dialogue sections that date the book.

I liked the relationship between Slade and his sergeant Clinton, but this too seems formulaic for an early GAD police procedural.  The comic Detective Sergeant is fairly standard in these types of mystery novels.  I wonder who was the first to have a murder mystery with the serious Detective Inspector in charge assisted by the somewhat whiny and comic sergeant.  Was it Wallace?  I haven't read enough of his books to know.

The villain is obvious from the start and his intricately thought out crimes and schemes are variously described as "fantastic" and "stupendous".  I'd use the adjective outlandish.  But of course it's fiction from a bygone era when these books were meant to thrill and excite. I guess in some ways it still succeeds.  I know my eyebrows were raised at a several points even if some of those surprises literally came in the last two pages in a written confession that explained two quasi-impossibilities related to the stabbing murder.

Gribble may be worth investigating in later Slade books or even in his many other mystery writing guises.  He also wrote as Leo Grex, Bruce Sanders, and several other pseudonyms.  The very first Gribble book, The Case of the Marsden Rubies (1929), is alluded to in the penultimate chapter. Though Gribble mentions one surprise plot element the villain of ...Marsden Rubies was -- thankfully -- not named.  It's a fairly easy to find book and I may sample one more tasting of Gribble and Slade in the future.  I know I have The Frightened Chameleon, a Slade mystery from 1950, somewhere in a box in this book museum. Stay tuned.
