A will. A death. A way to go. It's 1884. Emma, now with a young son and no longer travelling with Daniel on the Mary B, is finding it difficult to settle into town life. Her outspoken views don't always go down well with the members of the Ladies Benevolent Society, and no one wants her herbal remedies with doctors in town

So when her dear friend Janet Pickles is arrested for murder, Emma is only too ready to spring into the fray, calling on all her instincts, knowledge, and good common sense to uncover the truth. But can she convince the coroner and the local police Sergeant that they've got it wrong? After all, she's managed a riverboat crew, so anything is possible. Isn't it?
