Found Wanting

One unremarkable winter morning, civil servant Richard Eusden is on his way to work in London when he is intercepted by his ex-wife, Gemma. She has sad news of his old friend, her other ex-husband, Marty Hewitson. Marty is dying, but needs one last favour done for him - now, today, at once.
Eusden reluctantly agrees. But what should be a simple errand soon it turns into a race for life - his and Marty's.It takes him across Belgium, Germany and Denmark and on into the Nordic heart of a mystery that somehow connects Marty's long dead grandfather, Clem Hewitson, an Isle of Wight police officer, with the tragic fate of the Russian Royal Family, murdered ninety years earlier.
