Let's pen down all we know about Mr. Bajaj till now
1 He is a ruthless businessman
2 He hates disloyal wives and doesn't associate himself with husbands of disloyal wives - This is understandable, none likes a disloyal wife, there is a possibility that his wife cheated on him, that makes him husband of a disloyal wife. Can we say that this Mr. Bajaj has detached himself from a Mr. Bajaj, who was cheated on by his wife? Interesting
3 Moloy Basu and Basu publication connection with his past - Just a guess
4 Alcoholic and has a good collection of alcohol
I am out, add if you have picked up more information about him, will help us understand his character in future
