Never underestimate a librarian.

Intelligent cosy crime with razor-sharp wit and an unlikely hero, for fans of P.G. Wodehouse and Muriel Spark

"So funny." Lynne Truss

Shona McMonagle is back, once again personally selected by Marcia Blaine, founder of her alma mater, the Marcia Blaine School for Girls – this time for a crucial mission involving time travel, Macbeth, the Weird Sisters and a black cat.

Unsure which version of history she’s in – and fully aware of Shakespeare’s egregious inaccuracies - Shona tries to figure out who she’s here to save. But between playing the Fool and being turned into a mouse, things don’t always go her way. Shona’s expertise in martial arts is put to the test as family tensions rise and fingers are pointed for murder.

Can Shona unravel the mystery in time to complete her mission? Never underestimate a librarian!
