'I'm here for her sake.
That's all.'
'Nobody asked you.'
'And now I'm here I won't be put off.'
Curly Delafield is back in Guildford for the first time in 12 years to look for his missing sister Sarah. The only clues are her coat and purse which were found on Eastbourne beach. Was it suicide? Murder? Or is there some other explanation?
Curly holds no brief for the Home Counties. He's going to find out - even if some feathers get ruffled in the process.
