FP 30,000. Charlotte and Thomas Pitt Mystery #31, following ANGEL COURT AFFAIR. Commander Thomas Pitt, head of Special Branch, is called to the scene of a brutal explosion in the heart of London. The bomb was set off during an important - and secret - police raid, killing several officers, and the government suspects anarachists. But what Pitt discovers is far more disturbing: the explosion was not a terrorist attack meant to sow chaos, but a calculated means to commit a targeted murder. And the evidence trail leads him straight to a deadly crime set in the drawing rooms of London's elite.
