No case is too strange or too baffling for the policeman George Felse and his son, Dominic. Over 13 instalments and two decades, the Felse Investigations will take them from their home on the Welsh Borders to the southernmost tip of India.

When archaeologist Alan Morris disappears in Turkey, his great-niece, Charlotte, regrets never having got to know him better.

But when Charlotte arrives she finds more than just a few old stones...

First there is a charming young man, coincidentally staying at the same hotel, who is very insistent on being her guide. Then a troublesome schoolboy disappears and a corpse is found. Detective Chief Inspector George Felse is called in to solve a mystery whose roots go back to ancient Roman times...
