"Toby and Elinor, brother and sister, friends and confidants, are sharers of a dark secret, carried from the summer of 1912 into the battlefields of France and wartime London in 1917. When Toby is reported 'Missing, Believed Killed', another secret casts a lengthening shadow over Elinor's world: how exactly did Toby die - and why? Elinor's fellow student Kit Neville was there in the fox-hole when Toby met his fate, but has secrets of his own to keep. Enlisting the help of former lover Paul Tarrant, Elinor determines to uncover the truth. Only then can she finally close the door to Toby's room." --Publisher description.
