A murder leads Sarah Burke to investigate a money-laundering ring with connections extending far beyond Tucson - but does the key to solving the case lie closer to home than she realises? The murder of a man seen fighting in a house during a Fourth of July street parade plunges Sarah Burke's whole household - her fragile mother Aggie, shrewd and ever-helpful live-in boyfriend Will and even her hard-charging niece, Denny - into her latest case. The investigation leads to a money-laundering ring with international connections, and Sarah and her smart, hard-working crew of detectives must follow the puzzle, set against the backdrop of Tucson's unique character - an ancient, beautiful valley with a polyglot ethnic community and a bilingual, modern city - without knowing where it might take them. Could the answers lie closer to home than she realises?
