P J Brooke is the amalgam of a husband and wife writing team, Philip O'Brien and Jane Brooke.
After a brief spell at the Foreign Office Philip taught Latin American studies at Glasgow University. He then moved to Latin America and witnessed some of its most dramatic moments: the Allende government and Pinochet's dictatorship in Chile, the cocaine wars in Columbia and the Chavez revolution in Venezuela. On his return to the UK he stood as a parliamentary candidate for the Scottish Green Party and was a member of the Scottish Constitutional Convention, which led to the formation of the Scottish Parliament.
Jane has had a somewhat quieter life, mostly in local government and consultancy. However she has also been involved with the Scottish Green Party and it was during her time as National Secretary that she met Philip.
