In March 1912 the Postmaster-General accepted the Marconi Company's tender to build the first six stations of a wireless chain to link up the British Empire. The negotiations had been conducted for the Marconi Company by the Managing Director, Godfrey Isaacs, brother of Sir Rufus Isaacs, the Attorney-General. Immediately it became clear that opposition to the contract would be unexpectedly strong. There was evidence of a gamble in Marconi shares.

Although it has been discussed in many biographies of the period, this is the first objective and full-length account of a dramatic and little-known event in English History.
