四名聪明的学生成立自己的侦探所，把冒险发布到播客上，成为彼此的可靠好友。

Frances O'Brien, devout Catholic and panic disorder sufferer, runs a very tight ship at the Middleton Interactive Learning Centre, a modern outer suburban Library. Always quick to point out she doesn't make the rules when in fact she does when it comes to her library. Despite the chronic vandalism, the dysfunctional staff and her own particular challenges with the ever-growing Muslim community, Frances wears her Head Librarian's badge with relish.
No more so than during the heady period leading up to Book Week - precisely the moment her life suddenly takes a turn for the worse!
