[Jane Watkinson · Rating 4 out of 5]

Fascinating story, pacy and impeccably researched, I really enjoyed this final book of the trilogy - or is it? I was invested in Margaretta’s story - a fictional character amongst historical figures. I was disappointed that she didn’t find love outside her family, so might there be another book to give us a satisfying ending?! GJ Williams has really found her stride now, but she really deserves a better proofreader. It was very annoying that Amelia/Amalia and Wooton/Wotton were not corrected, even given the variety of spellings in Tudor times!! Also many other slips of spelling and grammar.

Outstanding. I wouldn't expect less from G.J Williams at this point. I have read all three Tudor Rose Murders books and I feel so immersed and invested in the charecters stories and lives. I hope there will be a fourth book to come.
