"Some adulterers do not wish to be discovered. They run, temporarily, for connubial cover
at the slightest whiff of danger. They hide their tracks. They perfect their untruths.
They confide in no one. They never write compromising letters, and destroy any that
they receive immediately after reading them. They are unfeignedly happy at home, and
are neither more nor less loving towards the spouse than in the days of innocence.
These are sunny, ardent adulterers, who have no intention of mending their deceitful ways;
yet they would leave the illicit beloved to be crushed beneath the wheels of a passing cart
rather than risk endangering their own domestic harmony."

Victoria Glendinning, Electricity (1995)
