When you think of spies, images of suave men in suits sipping martinis tend to come to mind - not, well, the Romans. But espionage has been used throughout Rome's history, from it's enemies using intelligence gathering techniques against the empire, through to even the most pragmatic of Emperor's recruiting secret agents. But what do we actually know about the Roman Secret Service, and how was it used across the empire?

Looking at it's uses in the Punic Wars, how different Emperors employed different tactics, and the archaeological evidence we have of their actions today - what did it take to be a Roman Spy, and how many of them were there actually?
