Lessons in Power

The ghosts of the past will shape your future. Unless you fight them.
*Cambridge Fellows Mysteries, Book 4*
Cambridge, 1907
After settling in their new home, Cambridge dons Orlando Coppersmith and Jonty Stewart are looking forward to nothing more exciting than teaching their students and playing rugby. Their plans change when a friend asks their help to clear an old flame who stands accused of murder.
Doing the right thing means Jonty and Orlando must leave the sheltering walls of St. Bride’s to enter a labyrinth of suspects and suspicions, lies and anguish.
Their investigation raises ghosts from Jonty’s past when the murder victim turns out to be one of the men who sexually abused him at school. The trauma forces Jonty to withdraw behind a wall of painful memories. And Orlando fears he may forever lose the intimacy of his best friend and lover.
When another one of Jonty’s abusers is found dead, police suspicion falls on the Cambridge fellows themselves. Finding this murderer becomes a race to solve the crime… before it destroys Jonty’s fragile state of mind.
*Warning: Contains sensual m/m lovemaking and hot men playing rugby.*

Learning the Ropes

Working for a company whose slogan is ‘Sex sells and we’re very good at sex’ isn’t easy for a man with an apparently inexhaustible ability to blush. Things only get more embarrassing for Floyd when he’s sent to construct an advertising campaign for a BDSM club.
As if that wasn’t bad enough, the owner of the club is Peter Ingram, the silent partner in SKIN designs, which technically makes him Floyd’s boss. If he screws this up, Floyd’s going to be looking for a new job. His only option is to set aside his embarrassment and throw himself into learning everything there is to know about leather.
But when Peter agrees to teach Floyd what submission really means, suddenly it’s not only his job that’s at risk.

Learning Python Design Patterns

Design pattern is a well-known approach to solve some specific problems which each software developer comes across during his work. Design patterns capture higher-level constructs that commonly appear in programs. If you know how to implement the design pattern in one language, typically you will be able to port and use it in another object-oriented programming language.
The choice of implementation language affects the use of design patterns. Naturally, some languages are more applicable for certain tasks than others. Each language has its own set of strengths and weaknesses. In this book, we introduce some of the better known design patterns in Python. You will learn when and how to use the design patterns, and implement a real-world example which you can run and examine by yourself.
You will start with one of the most popular software architecture patterns which is the Model- View-Controller pattern. Then you will move on to learn about two creational design patterns which are Singleton and Factory, and two structural patterns which are Facade and Proxy. Finally, the book also explains three behavioural patterns which are Command, Observer, and Template.
Approach
This book takes a tutorial-based and user-friendly approach to covering Python design patterns. Its concise presentation means that in a short space of time, you will get a good introduction to various design patterns.
Who this book is for
If you are an intermediate level Python user, this book is for you. Prior knowledge of Python programming is essential. Some knowledge of UML is also required to understand the UML diagrams which are used to describe some design patterns.

## Who This Book Is For
This book is for Software architects and Python application developers who are passionate about software design. It will be very useful to engineers with beginner level proficiency in Python and who love to work with Python 3.5
## What You Will Learn
* Enhance your skills to create better software architecture
* Understand proven solutions to commonly occurring design issues
* Explore the design principles that form the basis of software design, such as loose coupling, the Hollywood principle and the Open Close principle among others

* Focus on the interaction between objects with the command and observer patterns
* Improve the productivity and code base of your application using Python design patterns
## In Detail
With the increasing focus on optimized software architecture and design it is important that software architects think about optimizations in object creation, code structure, and interaction between objects at the architecture or design level. This makes sure that the cost of software maintenance is low and code can be easily reused or is adaptable to change. The key to this is reusability and low maintenance in design patterns.
Building on the success of the previous edition, Learning Python Design Patterns, Second Edition will help you implement real-world scenarios with Python’s latest release, Python v3.5.
We start by introducing design patterns from the Python perspective. As you progress through the book, you will learn about Singleton patterns, Factory patterns, and Facade patterns in detail. After this, we’ll look at how to control object access with proxy patterns. It also covers observer patterns, command patterns, and compound patterns.
By the end of the book, you will have enhanced your professional abilities in software architecture, design, and development.
## Style and approach
This is an easy-to-follow guide to design patterns with hands-on examples of real-world scenarios and their implementation in Python v3.5. Each topic is explained and placed in context, and for the more inquisitive, there are more details on the concepts used.
