Sometimes a phrase or a sentence sticks and resonates with you; you wish you could write such a description. Here is how Parker described double agent Kim Philby and le Carré’s father.
“But both men were double-sided, truth-inverting, charismatic, untainted by empathy, profoundly destructive, and finally incomprehensible.”
