From Sherlock Holmes Esq to Dr J Watson:
Watson – I need you to do one small thing before we meet next; you will find a package awaiting when you eventually find your way homewards – on no account open said item; control your natural and inherent curiosity by any means possible – visit Mrs Wetherbucket’s Academy for Wayward Young Ladies if you have to, but Do Not – I repeat DO NOT, even infinitesimally, open what you find sitting on your dining-room table.
Your life depends on your carrying out this simple instruction. I hope to find you hale and hearty when we renew our friendship.
SH.
