The Butterfly Conspiracy by Vivian Conroy

The Butterfly Conspiracy (A Merriweather and Royston Mystery, #1)

by Vivian Conroy

Perfect for fans of Deanna Raybourn’s Veronica Speedwell mysteries comes the enchanting series debut from Vivian Conroy, The Butterfly Conspiracy.

In late Victorian times, when new inventions cause both excitement and terror, a mysterious death at a zoological lecture brings together two unlikely allies in a quest through London's upper crust and underbelly to unravel the ingenious murder method and killer behind it.


Miss Merula Merriweather is not like other women her age: instead of hunting for a husband at balls and soirees she spends her time in a conservatory hatching exotic creatures. As the Royal Zoological Society won't accept a woman's accomplishments, she has her uncle Rupert take credit for her achievements. But at a zoological lecture, the guest of honor dies after contact with one of Merula's butterflies, and Merula's uncle is arrested for murder.

In an attempt to safeguard evidence to prove his innocence, Merula almost gets killed but for the timely interference of enigmatic Lord Raven Royston. Viewing natural history as a last resort to regain respectability lost by too many dubious business investments, Raven didn't expect his first lecture to take a murderous turn. Feeling partially responsible because he encouraged Merula to release the gigantic butterfly from the glass case in which it was kept, Raven suggests they solve the puzzle of Lady Sophia's sudden death together by looking closer at her relations with estranged friends, long suffering staff and the man groomed to be her heir, so close to her money and yet unable to touch any of it.

With the police looking for them, and every new discovery raising more questions than answers, especially about the murder method which left no traces of foul play on the body, Merula will have to risk her own life to get at the truth and save her uncle from the gallows in The Butterfly Conspiracy, Vivian Conroy’s enchanting series debut.

A captivating historical cozy mystery, The Butterfly Conspiracy is an excellent debut to a new series! Suspenseful and thrilling, I was immediately sucked into the Victorian world superbly created, with intriguing characters and a puzzling plot that kept me turning pages.

I liked the dynamic between Royston and Merula. She's wasn't a passive Victorian flower, he wasn't a man strong-arming her into being a passive Victorian flower. Although the possibility for a romance was hinted at, it wasn't overt and took a backseat to the plot. I appreciated that, just like in food, the best flavors are in the background as an enhancement. It also leaves the door open to future story lines, and I look forward to seeing how their relationship develops.

The plot was intriguing; at a zoological meeting, Merula unveils the exotic butterfly she has cultivated. Because she is a woman, Merula's Uncle Rupert agrees to take the credit, but when a woman dies after the butterfly lands on Lady Sophia's arm and she falls over, dead, Uncle Rupert is accused of murder. Determined to clear his name, Merula teams up with Lord Royston, uncovering many motives and suspects while pursued by the police. I have no idea if the method of death is feasible or not, but it wasn't something I've ever seen before and really enjoyed it, as well as the surprising and exciting ending.
