A Perilous Undertaking by Deanna Raybourn

The first book in this series was fabulous. Ms. Raybourn's interview with the Smart Bitches was fantastic. And this book continues a streak.
Veronica Speedwell is back. And bored. She's very bored. Just spending her days training with Revelestoke "Stoker" Templeton-Vane is not how she wanted to be spending her life. But their friend Lord Rosemorran who was going to finance an expedition for all of them tripped over his pet tortoise (yes!) and broke his femur. So when Lord Rosemorran's sister asks Veronica if she wants to go to the Curiosity Club, Veronica doesn't hesitate. Curiosity is the theme of this book and mentioned quite often in conjunction with our heroine.
It's what springs to the fore when she realizes that she has actually been tricked into meeting with one of her aunts. One of her father's sisters. The father who has never been able to publicly acknowledge her. This aunt wants her to help clear up the name of Miles Ramsforth, a man who is about to hang for murdering his pregnant mistress.
The mystery is well developed, we get to learn a lot more about the characters of both Stoker and Veronica (what they have in common, a little bit more about Stoker's past with his soul-sucking wife), and we get to meet the shadowy figure behind Sir Hugo Montgomerie, the head of Special Branch, Scotland Yard.
