In any normal situation, Cass would have stepped in and tried to calm Lettie himself, yet somehow this time, he though it wisest to let Miles take over and handle the situation. He obvioiusly knew what to do, and instead Cass listened, pieceing things together, making sure to take note of what to do.
Like make sure to bring the notebook on any date with Lettie.
Most importantly though, was what she was telling him about Massimo, and the more he listened, the more Cass added to the immage. Italian, not Spanish, wife who was unfaithful...but it was the last piece of the puzzle that finally made him inwardly swear. Naples. That was not good, not if it was the man he suspected it was.
Report or no report, there was no way in hell that the Italian authorities would even think of prosecuting the man, not for a crime not commited on Italian soil, or with iron clad proof. He was far too influencial for that.
Still, he'd go, take the chance to visit Emilia's villa while nestling himself into the household and see what he could find out. If only to find evidence that it really was him who had done it and not some other man. Massimo was a fairly common name after all. He could be wrong.
When she asked why she couldn't remember, he sighed, but he didn't interfear. This way was a far supperior way to get information, and Miles seemed to be handling the situation well. If he suddenly started to fail, he'd think twice about staying in the background.
