They had caught the person, so the interrogation was quite straightforward.
Everyone in the Prince Mansion knew of the methods of the Prince Mansion Guards; the stable boy had already broken a leg and dared not resist, spilling everything.
In Safety Alley, there was a Wang Mazi who had approached him recently, inviting him out for drinks, and even to the Flower Tower, and had heard his mother was sick, giving him ten taels of silver.
It was just to inquire about some little things concerning the young master of the Prince Mansion, what the young master liked to do or eat. After the inquiry, he gave him one hundred taels of silver, which he, of course, happily accepted.
He heard that the flowers in the garden were being changed frequently, so he invited Ah Fu for a drink and, taking advantage of him being drunk, asked about it. Ah Fu, unguarded, spilled everything.
When he realized this matter had to do with the young master, he quickly reported it to Wang Mazi.
