Singing stones? Cars turning into dragons? All in a day's work for the Grey, Plymouth's secret defence against paranormal attacks in the city. But things take a serious turn when Frank, the Grey's leader, mysteriously disappears. With the rest of the Grey making sure the city's weirdness level doesn't hit critical, it's up to Alex, Frank's grandson, to search for answers in the Grey's potentially deadly, historical Archive. Can the current problems be related to the 'Strawberry jam' urban myth that originated in Victorian times? Or even the strange issues Brunel encountered while building the Albert Bridge across the River Tamar? But as Alex discovers, the answers lie even further back in the history of the Grey. Back to the 17th Century and the introduction into Britain of the 'China drink'. And to a secret war being fought underneath Plymouth Hoe.
