London basks in the June sunshine, with inhabitants and visitors alike looking forward to the great sporting events of the summer, but it brings problems for Scotland Yard and Commander George Gideon. Will there be an attempt to "fix" the Derby? Will the appearance of a South African team trigger political demonstrations at Lords? Then there is Wimbledon, with the chance that a young black American, unknown and unseeded, might battle through to the top. But will something happen to prevent him? Sequel to "Gideon's power", followed by "Gideon's art".
