The 1939 Arsenal side is firing on all cylinders and celebrating a string of victories. They appear unstoppable, but the Trojans - a side of amateurs who are on a winning streak of their own - may be about to silence the Gunners.

Moments into the second half the whistle blows, but not for a goal or penalty. One of the Trojans has collapsed on the pitch. By the end of the day, he is dead.

Gribble's unique mystery, featuring the actual Arsenal squad of 1939, sends Inspector Anthony Slade into the world of professional football to investigate a case of deadly foul play on and off the pitch.
