Artemis concentrated on the wall. Slate-gray, except for a network of jagged cracks that sundered the plasterwork.
A memory presented itself of six-year-old Artemis and his father walking the estate. As they passed the barn wall on the upper pasture, young Artemis pointed to the wall and commented. “See, Father? The cracks form a map of Croatia, once part of the Roman, Ottoman, and Austrian Habsburg empires. Were you aware that Croatia declared its independence from Yugoslavia in 1991?”
There it was. On the wall behind Pip and Kip. A map of Croatia, though fifteen-year-old Artemis saw now that the Dalmatian coastline was truncated.
They are on the Fowl Estate, he realized.
