Margaret the sheep

Margaret the sheep loves gossip and taking care of people at the office. She doesn't look it, but she's very much into true crime shows. (We're looking for a bit older, motherly voice. A British English accent is welcome, but not required)

Audition lines (the Duck is just for context): 

• Sheep :) = Yes, dear?        
• Duck :) = I'm Eugene McQuacklin, detective, and I need to ask some questions.        
• Sheep :D = A detective? How exciting!        
• Sheep :D = What's the most gruesome murder you saw?        
• Sheep :D = How many dead bodies have you seen?? 

•  Sheep :) = To be honest, everyone was quite shocked by the lunch theft. 
• Sheep :( = And no one told me they've called a detective! 
• Sheep :( (panicking) = I don't know what's going on at all!!
  
  
  
• 3 idle breathing sounds, that sound a bit sheep-like (she's baking a cake)
