Detective Sergeant Kathleen Doyle had recovered from the injuries she'd sustained when the marina balcony collapsed, but it was becoming more and more clear that there'd been quite a bit going on, whilst she'd been unconscious for a few days. For starters, there'd been some sort of donnybrook at the hospital, and as a result Acton had been placed on leave--not to mention that one of her nurses had disappeared. But these troubling developments couldn't hold a candle to the spectacle of Acton, behaving all mild-as-milk and seemingly content in his current role as househusband. It appeared that Doyle had her own mystery to solve--what on earth had happened, so that the world had turned upside-down? And what could her husband--who'd never been mild-as-milk a day in his life--be up to?
