A Dangerous Collaboration (Veronica Speedwell Series, Book #4) by Deanna Raybourn

Lured by the promise of a rare and elusive butterfly, Veronica Speedwell is persuaded by Lord Templeton-Vane, her colleague Stoker's brother, to pose as his fiancee at a house party on a remote Cornish isle owned by his oldest friend, Malcolm Romily.

But one question hangs over the party: What happened to Rosamund? Three years ago, Malcolm's bride vanished on their wedding day. Now those who were closest to her have gathered, each a possible suspect in her disappearance.

From the poison garden kept by Malcolm's sister to the high towers of the family castle, the island's atmosphere is full of shadows, and danger lurks around every corner.

Determined to discover Rosamund's fate, Veronica and Stoker match wits with a murderer who has already struck once and will not hesitate to kill again.
