To answer the old one, it was Amy, the maid. She was at a herbalist, and could have gotten poison from herbs. Obviously Mr. Red would trust her when he was drinking tea with poison in it. Ronald strangled Mr. Red when he thought Mr. Red was asleep, but really he was dead. And then Mrs. Red stabbed him when she thought he was sleeping with a knife from the cooking convention. The order could have been switched, but use common logic. Amy would probably not force the poison down Mr. Red when he was sleeping, because the poison took time and Mr. Red could be suspicious. If Mrs. Red had murdered Mr. Red, then both Ronald and Amy would see the knife. Ronald knew the strangling would be quick, so decided to strangle him when he was sleeping. In end, everyone attempted to murder Mr. Red.
Gommess got the person, but for wrong reasons, and JMJ got a closer reason, but the wrong person. So they both get a chimp.
The new case is up!
