A mysterious manuscript lands on the desk of the step-son of the late Dr Hugh Meredith, a country doctor with a prosperous and peaceful practice in a small English town. From the written account he has left behind, however, we learn that Meredith was haunted by events that took place years before, during his training as a junior doctor near London’s Fleet Street, in a neighbourhood virtually unchanged since Dickens’s times.
Living then in rented digs, Meredith gets to know two other young medics, who have been carrying out audacious and terrifying research and experiments. Now they need the help of another who must be a doctor capable of total discretion and strong nerves.
‘Remember that what you know you can never un-know. If you are afraid, then…’
A gripping and suspenseful mystery by one of the masters of the genre…

A new and extensively revised edition of a popular textbook used in universities, coding boot camps, hacker clubs, and online courses.
The best way to understand how computers work is to build one from scratch, and this textbook leads learners through twelve chapters and projects that gradually build the hardware platform and software hierarchy for a simple but powerful computer system. In the process, learners gain hands-on knowledge of hardware, architecture, operating systems, programming languages, compilers, data structures and algorithms, and software engineering. Using this constructive approach, the book introduces readers to a significant body of computer science knowledge and synthesizes key theoretical and applied techniques into one constructive framework.The outcome is known known as Nand to Tetris: a journey that starts with the most elementary logic gate, called Nand, and ends, twelve projects later, with a general-purpose computer system capable of running Tetris and any other program that comes to your mind.
The first edition of this popular textbook inspired Nand to Tetris classes in many universities, coding boot camps, hacker clubs, and online course platforms. This second edition has been extensively revised. It has been restructured into two distinct parts—Part I, hardware, and Part II, software—with six projects in each part. All chapters and projects have been rewritten, with an emphasis on separating abstraction from implementation, and many new sections, figures, and examples have been added. Substantial new appendixes offer focused presentation on technical and theoretical topics.
