The coiners' quarrel

A Sir Geoffrey Mappestone mystery Westminster, 1102. About to depart for the Holy Land, Sir Geoffrey is suddenly summoned back by the King. When he arrives at Court he finds two argumentative groups of Saxon moneyers, one accusing the other of devaluing the King's currency. But is there more to it than greed? Geoffrey has no choice but to accept the King's commission to investigate whether this is part of a treasonous plot.
