Haldane in Constantinople - 1936

The awaited email came through from my editor last night - subject: delivery.
I'm homing in, just entered the last chapter of my book on J. S. Haldane. He never let up - this photograph sees him on the walls of Constantinople in the last month of his life, at the end of a vigorous round the world working tour. The aim for this last chapter is that it also goes expansive, giving something of his visionary breadth.
