The Case of the Reincarnated Client is the fifth and most recent (2020) in the Vish Puri (and Mummy-ji!) series by Tarquin Hall. It has dropped to $1.99 at Kindle US, not at Kobo US, at least as of now. Although they go on sale from time to time, this series is usually priced at over $10 in the US, so grab it now if you want it.
I've read and really enjoyed the first three in this series, so happy to see this one on sale. And the third one even inspired me to learn how to make butter chicken in my slow cooker!
