Today I was reading The Dog Who Came In From the Cold (a Corduroy Mansions novel) by the same author, and I came across mention of a tea I had never heard of before. I googled "Malawian Lost Tea" and soon traced it to an African tea being sold by the Rare Tea Company under the name of Lost Malawi Tea.
This is how they describe it: "To compare this to an ordinary tea would be like comparing a line-drawing with a sculpture. This is like drinking normal tea but in 3-D." Wow. Furthermore, "Each tin comes with a short story by Alexander McCall Smith." Well, well, WELL!
