The man was on a night shift (22hrs-06hrs) but suddenly felt unwell and knocked off early.
After being attended to briefly at the clinic, he retired home.
When he arrived at his house he found a strange car parked in his yard and his little investigations quickly revealed the wife was with another man.
The wife was shocked that the husband had come early and actually caught them in bed.
She begged for mercy and pleaded with the husband to forgive her.
But the husband told the cheating wife to leave his house peacefully.
The wife however requested to be allowed to leave in the morning as it would be dangerous to leave in the night, she begged.
The husband allowed her to stay the night in the house and slept in the children's bedroom.
Later the man woke up to a burning fire that nearly killed him.
It has now been established that the cheating wife attempted to burn him to death than suffer the embarrassment awaiting her in the morning.
Investigations point to a petrol keg from the garage she used to light the house.
The woman has been arrested for arson and murder of the children that failed to survive the burning inferno.
