A conspiracy of violence

The dour days of Cromwell are over. Charles II is well established at White Hall Palace, his mistress at hand in rooms over the Holbein bridge, the heads of some of the regicides on public display.

London seethes with new energy, freed from the strictures of the Protectorate, but many of its inhabitants have lost their livelihoods.

One is Thomas Chaloner, a reluctant spy for the feared Secretary of State, John Thurloe, and now returned from Holland in desperate need of employment.

His erstwhile boss, knowing he has many enemies at court, recommends Thomas to Lord Clarendon, but in return demands that Thomas keep him informed of any plot against him.

But what Thomas discovers is that Thurloe had sent another ex-employee to White Hall and he is dead, supposedly murdered by footpads near the Thames.

Chaloner volunteers to investigate his killing: instead he is despatched to the Tower to unearth the gold buried by the last Governor.

He discovers not treasure, but evidence that greed and self- interest are uppermost in men's minds whoever is in power, and that his life has no value to either side.
