The Strange Case of Hellish Nell, Nina Shandler, 2006 softcover, first edition, Da Capo Press publishers, very good conditon.
On March 23, 1944, as the allied forces prepared for D-Day, Britain's most famous psychic, Helen Duncan - Nell to her family - stood in the dock of Britain's highest criminal court accused of ... witchraft. It was a trial so bizarre that Winston Churchill grumbled, "Why all this tomfoolery?". But the Prime Minister was not privy to the Military Intelligence agenda fueling the prosecution: Duncan's seances were accurately revealing top-secret British ship movements. The authorities wanted "Hellish Nell" silenced.
