This is Terrance Dicks' best novel for some time. As usual, the author has returned to some of his favourite stomping grounds, including a flashback for the Second Doctor in World War One. The Sixth Doctor and Peri arrive in South Africa just an assassin takes a pot shot at the young Winston Churchill. Having saved Churchill's life, the Doctor believes that more sinister forces are at work, manipulating the actions of the Boers. Hindsight is the Doctor's greatest ally and his greatest fear: how much must he interfere to insure Churchill's future? Events come to the fore in the 1930s, spurred on by the intrigues of the Nazis, accompanied by the mysterious assassin... This is an excellent adventure story, very much in the mould of Indiana Jones or even Colonel Blimp. Familiar faces from the past reappear to aid the Doctor,and the 'Players' may turn out to be very old enemies indeed... Despite believing the Doctor to be an archetypal character, Dicks has got the Sixth Doctor exactly right here. This may even be the Sixth Doctor at his best, and it's a pity that it's never going to be on TV, for Dicks allows the Doctor to ditch that dreadful coat, to be replaced by a costume that Colin Baker might have preferred. 'Players' surpasses 'Exodus': although it employs real life characters from the same period, its overall slant is contrary to the earlier book and far more tasteful. I gave this a high mark because I didn't expect to enjoy it, but I did. However, Terrance Dicks could win higher marks if only he tried to do something a bit more original.
