Caught Napping

His companion was an alluring blonde solicitor. The body language told me they were not on a case. I’d been spotted, so bravely approached. The old philanderer, adept at quick thinking on his feet, gave me no time to speak: “Amanda and I do this from time to time my boy. Mums the word?” tapping the side of his nose. I’ve been bound to silence ever since until now.
