`The Mesmerist's Apprentice' is the sixth Victorian Murder Mystery by Lee Jackson, now known as L M Jackson, and one can see how his skills and characters have developed (although I still have a particular fondness for his first book, `London Dust').
The first point to be noted is that Lee knows his subject; his books are placed in a real world with real people, real locations and accurate backgrounds, clothing, food and transport. Not for him the somewhat Gothic or whimsical world of writers like Charles Dickens, here we have reality. Anyone who knows London can trace his characters movements through streets that were and, in many cases, still are. In fact, Lee as an academic is the author of `A Dictionary of Victorian London: An A-Z of the Great Metropolis,' which is the textual version of his website mentioned below.
The second point is that Lee is fast becoming a consummate artist at the twist in the plot; the sudden realisation that overturns all we have started to imagine or assume. It is a treat to read his books knowing that your assumptions WILL be overturned and wondering how it will be achieved. Excellent!
I recommend all of Lee's books to those who are fascinated by the realities of Victorian London (see Lee's website victorianlondon.org) and enjoy a good murder mystery with surprising twists.
