The Twist of a Knife

'Our deal is over.'

That's what reluctant author Anthony Horowitz tells ex-detective Daniel Hawthorne in an awkward meeting. The truth is that Anthony has other things on his mind.

His new play, Mindgame, is about to open in London's Vaudeville theatre. Not surprisingly Hawthorne declines a ticket.

On opening night, Sunday Times critic Harriet Throsby gives the play a savage review, focusing particularly on the writing. The next morning she is found dead, stabbed in the heart with an ornamental dagger which, it turns out, belongs to Anthony and which has his finger prints all over it.

Anthony is arrested, charged with Throsby's murder, thrown into prison and interrogated.

Alone and increasingly desperate, he realises only one man can help him.

But will Hawthorne take his call?
