Stuffed Cabbage

I think the smell is coming from the stuffed cabbage room, Andrea said.
Inspector  Barlow asked why there was an entire room full of cabbage.
Before she could answer, Armando burst in, announcing the Mrs. is lying in the fertilizer bin.
Was she breathing, her half sister Margo asked.
The man flushed and admitted the stink forced him to retreat without checking.
Sir Whitely suggested they examine the stuffed cabbage room for clues.
I run this investigation, the Inspector barked. We will question all of the dinner guests, one by one, in the sitting room.
Sir, interrupted Browning the butler, there are no chairs in the sitting room.
How can people sit in the sitting room without chairs, asked Alistar, the defrocked minister with a drinking problem
The stench grew worse.
Martin, the host's husband, suddenly broke into sobs. I hadn't seen her since the appetizer and never reported it.
The Inspector eyed him suspiciously.
May I ask, sir, were you having marital problems?
The man broke down and admitted he was having an affair with Maggie the maid.
All that cabbage, mused Sir Whitely, can destroy a gastric system. Just saying.
Browning explained further. The sitting room chairs have been moved to the dining room to accomodate guests.
Elementary, muttered the Inspector, lighting his pipe. He took a deep breath and puffed fast. He was readying himself for the fertilizer.
