Taken in Death [EPUB ebook] 

‘The evil witch killed Darcia. Henry knew it because he’d seen Darcia on the floor, and all the blood. Everything felt funny and sleepy and wrong. He knew he was under a spell. The evil witch’s magic spell.’When twins Henry and Gala are kidnapped and their nanny killed, Lieutenant Eve Dallas steps in to take control. But video footage shows what appears to be their mother arriving and leaving with the obviously drugged seven-year-olds. Something is wrong, and Eve, her husband Roarke and her brilliant team are ready to work round the clock to get the children back alive…Set between Thankless in Death and Concealed in Death.
