Dead Man's Time (Roy Grace #9, Peter James

A vicious robbery at a secluded Brighton mansion leaves its elderly occupant fighting for her life. Millions of pounds’ worth of valuables have been stolen.

Within days, Grace is racing against the clock, following a murderous trail that leads him from the shady antiques world of England, across Europe and all the way back to the New York waterfront’s gang struggles of 1922, chasing a killer driven by the force of one man’s greed and another man’s fury.
