The fate of the allied forces lies in the hands of Joanna and the Watsons in the next Daughter of Sherlock Holmes mystery from USA Today bestselling author Leonard Goldberg.During a critical stage in World War One, the Governor-General of South Africa journeys to London for a meeting of The Imperial War Conference. Days prior to the conference, the Governor-General is scheduled to have an audience at Buckingham Palace at which time a most precious blue diamond will be presented to King Edward as a symbolic gesture of the colonies’ resolute and never-ending allegiance to England.
The flawless blue diamond, with its magnificent luster, weighs nearly 3000 carats which renders it one of the world’s largest and most valuable gems. On the Governor-General’s arrival, he is ensconced at the fashionable Windsor Hotel under the tightest security, with his entire entourage and formidable security team occupying the entire penthouse floor. All entrances and exits are locked down and closely guarded, and no one is allowed entrance after 6 PM.
Despite the extreme precautions, the famous diamond is stolen from the Governor-General’s suite in the middle of the night, with no clues left behind. With Scotland Yard baffled, Joanna and the Watsons are called in to investigate the theft and it becomes clear that the crime is not simply the work of a master thief, but one that could greatly aid the Germans and turn the tide of war in their favor. Time is of the essence and the blue diamond must be recovered before it begins its travels which could cause irreparable damage to the allied war plans.
Up until this entry of this series featuring Joanna (Holmes) Blalock Watson, the Daughter of Sherlock Holmes of the series title, it has very much seemed as if the books in the series have been as much, or even more, in dialogue with Sherlock Holmes himself and the canon of the elder Dr. Watson’s accounts as they were about the investigations conducted in the series’ present by Joanna Watson with the able assistance of her husband, the younger Dr. Watson, and his esteemed father.
But in this entry in the series, even though it does call back to the codebreaking in her father’s Adventure of the Dancing Men, is finally dealing directly with the important events of her day rather than her father’s famous cases.
That is because The Blue Diamond takes place in 1916, and the criminal activities that Joanna and the Watsons are called in to investigate in London are directly related to the war taking place in Europe – even if that is only a suspicion when they are first called in.
At first, it looks like a series of very high-end thefts occurring at equally high-end hotels. The first prize the clearly expert thieves took was a rare Ming vase worth over 100,000 pounds. The second was an even rarer – and much more highly prized – blue diamond. Hence the title of the book.
But the diamond was stolen from the suite of the Governor-General of South Africa – making the whole mess a political nightmare. Even so, the theft of a rare vase and an even rarer diamond are still property crimes – even if the value of the items represented riches beyond the dreams of avarice – if not beyond the dreams of high-end thieves.
The third item stolen shifted the entire investigation from mere grand theft to treason when top secret papers were extracted from a visiting French Minister’s suite. Those papers, which contained top secret plans for a joint operation between the British and the French designed to draw the German army into a trap and then break them in a pincer movement, elevated the crime to one that would get the perpetrators hung – if Joanna and the Watsons can figure out who they are.
And as much as Scotland Yard wanted Joanna and the Watsons on the original case, MI5 was even more eager to have them discover not just whodunnit, but how and why and especially whether or not those plans had been relayed to the enemy.
The tide of the war depended on those answers. It really, truly did.
Escape Rating B: This series always gives me mixed feelings. Probably because at least within the confines of my own head, it is in dialogue with two other series (Mary Russell and Lady Sherlock) that re-work Holmes and each treats the Great Detective entirely differently. (If anyone knows of a story or even fanfiction that puts Joanna, Charlotte and Mary in the same room for what would be an utterly fascinating conversation please let me know!)
Only the Russell series has fully traveled beyond the original canon by virtue of having Sherlock outlive it. Lady Sherlock is still working her way through it. This is the first case of Joanna’s where she is dealing fully with her own contemporary circumstances and not her father’s.
Rather than being rooted in Sherlock Holmes’ old case, this one is rooted in what we now call history. It’s 1916, the Great War is creating great casualties along with victories that seem like defeats. The U.S. has not yet entered the war, and Germany seems unstoppable. The situation is grim. Those plans have the potential to change the tide of the war – but only if the Germans don’t see them (This eventually happened, the plans referenced in the story were carried out at the Battle of Amiens.)
At first, there are few clues beyond the obvious, that stealing the plans benefits the German High Command. If the plans reach Berlin it gives the enemy knowledge of future military strategy. It has the potential to demoralize the Allies. The uncertainty about whether the plans have been seen and/or tampered with throws up confusion and doubt.
While Germany’s motives are obvious, there don’t seem to be any German agents involved. Instead it all circles back to the South African Governor-General and his entourage. South Africa is a Dominion of the British Empire – an ally. And that’s where the case gets more convoluted.
As Joanna becomes more certain that the thefts were an inside job, the reasons for those thefts becomes that much more elusive. It’s only as the noose tightens around 221B Baker Street that Joanna is finally able to determine who is holding the rope – and why.
There are things about this series that I really like, particularly the portrayal of Dr. Watson Sr. as an intelligent man and a dedicated physician who misses his old friend and finds delight and purpose in helping his friend’s daughter and his own son continue in their footsteps. He’s delightful and he feels both real and right as a character. That he’s well into his 80s at this point in the series and has a heart condition makes me sad. He can’t live forever and there are signs that his time is coming.
I want to say that I find Joanna a bit odd – but she comes by that honestly, considering who her father was. Or does she? That, for me, is the greatest puzzle of the entire series so far, as Joanna seems to have every single one of her father’s habits, quirks and eccentricities to the point where she can seem to be a caricature of a man she never met. That she might have inherited his genius would be entirely possible – but not the whole kit and kaboodle of his personality in all its extremities. Rather than ringing true, this particular bell is ringing cracked.
The case she has to solve here is every bit as contrived and convoluted as any that her father faced. But at least this one is hers, born out of the war the world is facing in her time and not his. This feels like a step forward for the series so I’m glad to see it.
In spite of those quibbles, and all the ways in which this series drives me crazy, I know I’ll be back for the next book in the series. I never can resist a Holmes story.
