The lady and the king

An emperor stumbled once on a lady
Full of beauty, honesty and modesty
He knew he will never have her
For he already had a loving queen.

But he wanted her happiness too much
So he asked one of his favoured ones
To give her the love and honour
Which he himself could not give her.

He did not knew that his favoured one
Had a dark soul as black as night
He tricked his own benefactor
Squeezed him out of his wealth.

Pretending he was wooing her to marry
Squeezed, showered the money on his girl
When he realized that he may get caught
He tricked the emperor, poisoned and fled.
