An experiment in treason

the long version

"In An Experiment in Treason, a packet of incendiary letters is stolen from the London residence of a prominent official, and turns up in the colony of Massachusetts. Why are the contents of the letters so controversial? Why has a suspect in the theft turned up dead? And what should Sir John do about his feeling that Benjamin Franklin himself is somehow complicit? While the tensions rise, Sir John and Jeremy search for answers - and find that justice isn't always served by the letter of the law."--Jacket.
