New York Times bestselling author Kelley Armstrong returns to Victorian Scotland in the latest in the genre-blending Rip Through Time series.
Modern-day homicide detective Mallory Mitchell has grown accustomed to life in Victorian Scotland after travelling 150 years into the past into the body of a housemaid. She’s built a new life for herself. Even though she works as an assistant to forensic-science pioneer Dr. Duncan Gray and Detective Hugh McCreadie, she considers them true friends. And with Gray in particular, perhaps, someday, something more.
Late one night, Gray and Mallory are summoned urgently to the home of Lady Adler, a patron of Gray’s undertaking business, and they assume there’s been a death in the household. But instead, they arrive in the midst of a seance with a ghost demanding Gray’s presence. The ghost is Lady Adler’s former maid, who had gone missing but now requests that Gray investigate her murder. Although Gray and Mallory are skeptical, they agree to look into the matter, whether she’s dead or alive. But unsure if there’s been a murder or not, unable to call out the medium as a fraud, and concerned for the fate of the young maid, Gray and Mallory are once again drawn into a mystery much more puzzling–and more dangerous–than it first seems.
An Ordinary Sort of Evil, book #5 in the excellent A Rip Through Time series, delivers the twisty mystery and terrific character moments that we’ve come to expect over the course of these books.
A quick explanation of the story so far: Mallory Mitchell, a Canadian homicide detective from the 21st century, stumbles through a time anomaly while visiting family in Edinburgh and finds her consciousness now inhabiting the body of a 20-year-old housemaid in Victorian Scotland. This housemaid words for Dr. Duncan Gray, an undertaker and scientist who assists the Edinburgh police with unusual cases, which is probably the best of all possible situations for Mallory to have landed in.
As the series progresses, Mallory adapts to her new life, and after sharing the truth about herself with Duncan and a few other close connections, she’s able to apply her detective skills in this new, strange world. Five books into the series, Mallory is established as Duncan’s assistant, although with her modern-day detective and forensic skills, she takes the lead for their investigations. Meanwhile, Mallory and Duncan’s professional closeness and personal friendship seems to be developing into something more, and yet Victorian standards related to class, race, and gender threaten to put an end to any deeper relationship before it can even start.
As An Ordinary Sort of Evil opens, Mallory and Duncan are summoned to a wealthy patron’s home in the middle of the night — not to investigate a murder, but because a ghost summoned during a seance has asked for Duncan by name. Or so the medium says: She claims that a maid working in the patron’s household has contacted her, and wants Duncan to investigate her murder. The problem is, the maid was last seen alive and well, and was believed to have left for new opportunities. Mallory and Duncan scoff at the spiritualism fad, but when a body turns up, they’re immersed once more in an investigation, trying to determine if this is in fact the missing maid, what happened to her, and how someone at the seance could have known of her death.
It’s an ordinary sort of evil. The kind people do every day, and never think twice. It’s just how you get ahead in life.
Once again, Kelley Armstrong skillfully blends an intriguing, unpredictable murder mystery with Mallory’s fish-out-of-water existence in a time not her own, while also keeping the character development moving forward and building upon everything that’s happened so far in the series. That’s a tough order to fill, but this author makes it work, and then some.
One of the delights of these books is seeing Mallory’s adjustment to life in Victorian times. For propriety’s sake, she must pose as Duncan’s subordinate and defer to him — publicly, at least — on matters in which she’s the expert. Behind closed doors, however, she lets loose and allows her outspoken nature to break free, which makes for all sorts of entertainment as we readers get to enjoy her anachronistic sass and snark.
I raise a slow middle finger.
“Too bad I do not know what that means,” he says. “I am certain, though, that it expresses your agreement with my point.”
The mystery in An Ordinary Sort of Evil is highly entertaining and not at all straightforward. I often thought I had a sense of how things might unfold; each time, I was wrong. Following Mallory and Duncan’s investigation is pure delight — I loved seeing how the clues and false leads and various suspects and their actions all come together by the end.
As for the characters and their relationships, things do progress in ways that will make readers of this series very happy, but there’s plenty of room for even more developments… and that’s all I’ll say about that!
A Rip Through Time continues to entertain and offer thrills and mysteries to puzzle through, and I can’t wait for more. Highly recommended — but do start at the beginning of the series! You won’t want to miss a thing.
Next up: A newly announced novella, to be release later this year. I absolutely plan to read it — I’ll need a Mallory fix while waiting for the next book in the series.
