The Indigo Tea Shop, Charleston's favourite spot of tea, has just come out with its latest flavour- Gunpowder Green. Theodosia Browning cannot wait to hear its praises as it is unveiled at the annual yacht race. But when she hears the crack of an antique gun meant to end the race, a member of Charleston's elite falls dead. Theodosia has a hunch that his demise was no accident - and will go out of her way to prove it. But if she doesn't act fast, Theo will find herself in hot water with some boiling-mad Charlestonians - and more than a little gun- chai . . .
