I happened on this bundle while on my way to something else - don't know how long it has been available, but I searched here on the forums and didn't find it either under "Fluke" or "Plum Pudding", so hopefully this isn't a double post.
The books are:
Plum Pudding Murder
Candy Cane Murder (a novella, in a set of three novellas - the other two by other authors)
Sugar Cookie Murder
The bundle is available at Kobo, Nook, Sony, B&N, and a few others.
I only did the price comparison at Kobo (and it appears to be discountable/couponable there, since it has two prices listed - although I didn't buy it myself):
bundle: $9.29
Plum Pudding: $4.99
Candy Cane: $4.39
Sugar Cookie $4.39
So it's about like getting one of the books for free. I assume it's similar at the other sellers.
