Question 158

Bee, Cee and Vee live in Microphyllia where there are only two types of creatures – those that consistently tell the truth and those that consistently lie. The former creatures are Trudees and the latter Falsees. When I last visited Microphyllia I asked Bee: “Who of you all are Trudees?”
Bee mumbled its answer so I didn't quite catch what she said.
“Bee said that only one of the three of us is a Trudee”, Cee noted.
Vee turned to me and said: “Don’t believe Cee, he’s not telling the truth”.
Who of them are Trudees and who are Falsees?
