The Twist of a Knife

When reluctant author Anthony Horowitz tells ex-detective Daniel Hawthorne that their agreement is over, he has other more urgent things on his mind.

His new play Mindgame is about to open at London's Vaudeville Theatre, but on opening night, Sunday Times critic Harriet Throsby gives the play a savage review.

The next morning she is found dead, stabbed in the heart with an ornamental dagger that has only one set of fingerprints on it. Anthony's.

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

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

But will Hawthorne take his call?
