Serial killer? Mad scientist? Capitalist espionage? Every time I thought I'd worked out what was happening in this excellent thriller my theory was thrown up in the air again! All this, plus a great duo in cop Columba and her expert adviser Dante, made for a fantastic read. Thank goodness the next in the series is just out.

Colomba hit the wall with her face and fell to the pavement. Her breath came back, along with a surge of sobbing.
'Oh, God," she said between sobs. 'Oh, God.'
Dante was right. There was a pitiess kidnapper operating in the shadows. There really was.
