The Last Remains - Elly Griffiths

When builders renovating a café in King’s Lynn find a human skeleton behind a wall, they call in DCI Harry Nelson and Dr Ruth Galloway to investigate.

The bones are identified as the remains of Emily Pickering, an archaeology student who went missing several decades ago.

Emily had been part of a group of students digging at Grime’s Graves, Norfolk’s famous Neolithic flint mines. Suspicion falls on her course tutor and another member of the group – Ruth’s good friend, Cathbad.

Then, just when the team seem to be making progress, Cathbad disappears. The race is on to find him and prove his innocence – but will Ruth and Nelson uncover the truth in time to save their friend?
