The Sandpit

When John Dyer returns to Oxford from Brazil with his young son, he expects a quiet life. Every day is the same. He drops Leandro at his smart prep school and walks to the library to research his new book. His time living on the edge as a foreign correspondent in Rio is over. But then the father of his son's friend, an Iranian nuclear scientist disappears, and Dyer was the last person to see him alive ... A clever contemporary thriller with shades of Graham Greene and John LeCarré.
