Book excerpt: Irma and Siiri go out with a bang in The End of Sunset Grove, the conclusion to Minna Lindgren's Lavender Ladies Detective Agency trilogy. A hilarious cosy crime mystery, perfect for fans of Richard Osman’s The Thursday Murder Club and M.C. Beaton. Best friends Irma and Siiri are relieved when they can finally return home, but things have changed in the retirement home . . . Sunset Grove is under new management, a sinister organization that promises spiritual enlightenment in return for donations from its residents. And the staff seem to have disappeared, replaced by technology that remotely takes care of all of their needs, if only they could work out how to use it . . . The Lavender Ladies are increasingly suspicious of the new order and plan an elaborate act of sabotage. But their last hurrah has some drastic consequences – will the Lavender Ladies get more than they bargained for?
