"Here's the address of Lucy Riley sir" A PC handed Barnaby a piece of paper.

"Thank you constable" Barnaby replied taking the paper from him.

"Come on Jones let's talk to the bit on the side" Barnaby instructed his sidekick.

"I think it's the ex sir." Jones offered his opinion.

"Let's keep an open mind Jones before guessing" Barnaby smirked.

The duo walked in silence to Lucy's address and knocked on the door.

A girl with short blonde hair answered "Can i help you?" She asked.

"Are you Lucy Riley?" Asked Barnaby

"I am, yes and who are you?" She asked abruptly.

"I am DCI Barnaby and this is my colleague acting DC Jones. May we come in Miss Riley?" Barnaby informed her.

"I suppose so" She gestured them both inside. "My dad will be back soon so you better be quick. He doesn't like coppers".

"Can we sit down?" Asked Barnaby.

"Yes but be quick" Lucy said.

"When did you last see Daniel Scott?" Asked Jones.

"Who's that?" She lied.

"Don't lie to us Miss Riley. We know you were both carrying on together and sneaking around behind his girlfriend's back" Barnaby said in disgust. He hated when people cheated on their partners.

"Fine, I saw him about a week ago. His girlfriend saw us sneaking about and she confronted us, she slapped me" She explained "I'm carrying Dan's baby. I'm about 6 weeks but my father doesn't know and he mustn't know" Lucy said.

"You have motive for murder" Said Jones.

"No i don't. It was me Dan loved not her. He dumped her for me and the baby. If anyone has motive it's Penny. Dan wanted to settle down with me and raise our child together and now..." She broke down.

"Do you need a tissue Miss Riley?" Asked Jones.

"Thank you" She replied taking a tissue from Jones "And now I'm going to be a disgraced single mother".

"We'll go now Miss Riley and leave you in peace" Barnaby said as they stood up.

When Barnaby and Jones got out the house Jones said "She is right though. Penny is top contender as suspect. She was dumped by Dan, and Lucy is carrying his child. I wonder if Penny knew about the baby?"

"We need to talk to her again and we need to talk to Lucy's father and see how much he knew" Barnaby informed Jones.
