For years, I've told her she should get her stories together and I've finally been listened to. The collection is called Akitada and the Way of Justice, and it is available as a Kindle. Probably other formats as well. Sadly, it seems like this is not a COMPLETE collection, but I believe it is every story that has been previously published in Alfred Hitchcock Mystery Magazine.
I've read most of the stories. Will I get this collection? Absolutely. Will I try to interview the author and find out more about the background and composing process? No doubt.
Now, the product description at Amazon is a bit too bare, of course, but that can be changed, I'm sure. Anyway, whatever the purchase price, you won't be disappointed.
