Worth the wait. The riddle element to the mystery was a nice touch. It was even better because I've been to several of the areas discussed.
A lot of the b-story and personal elements surrounding the core mystery made me think this might be the end of the series. The author has split her time with a new series, so there's only one Penny Green each year. There's more to explore with Eliza's divorce and budding romance, which could mirror some of what James went through with Charlotte and Penny. If she continues to be a reporter, Penny will have to work under a pseudonym as a freelancer, which still leaves the door open to more mysteries. With that, comes the added drama it would cause for James as Victorian values would be quite harsh on him, seeing him as a weak and ineffectual provider or something.
One of the main criticisms of feminism is that it's never adequately reconciled the biological imperatives of motherhood with being a career-oriented, independent woman. I think it's something like 90% of a woman's eggs are gone by the time she turns 30. At 35, if Penny and James do have a kid, it will probably be just the one, and I imagine it would feel like a miracle baby to both of them. I've had female friends in a similar situation, where they were confident that they'd go back to work, but once the baby arrives, it changes everything. I could see Penny apply the same passion and tenacity she has for her mysteries to her child. While her relationship with her sister has been a bit rocky, I think it would spark the idea that her first child should have a sibling. All of these things bring new drama, and higher stakes as kidnapping or the death of a child would enter the mix as the family expands.
Because this story ends with a wedding, I'm curious to see how the Green sisters continue to navigate these two competing forces of independence and family. We got a glimpse of this as Penny had to deal with Mr. Conway in this story, but I hope we're in for a more in-depth exploration - especially if Mrs. Conway tries her hand at being a columnist.
If Penny is unable to become a mum, I think it might be interesting to see her try her hand at becoming a private detective. She's already got experience going undercover and dealing with dangerous people.
The missing father storyline has been bubbling throughout the series, and it was so wonderful to see it finally come to the forefront a bit. Hopefully, the zinger dropped at the end of this story means there is another installment as there's so much left to explore.
All in all, this was a great installment to a wonderful series and I really do hope it continues.
