The Chestermarke Instinct

The Chestermarke Instinct is a mystery about a brilliant detective who investigates the disappearance of a bank manager and some priceless jewelry. Excerpt: "Every Monday morning, when the clock of the old parish church in Scarnham Market-Place struck eight, Wallington Neale asked himself why on earth he had chosen to be a bank clerk. On all the other mornings of the week, this question never occurred to him: on Sunday he never allowed a thought of the bank to cross his mind: from Sunday to Saturday he was firmly settled in the usual rut, and never dreamed of tearing himself out of it. But Sunday's break was unsettling: there was always an effort in starting afresh on Monday."
