But I'm booooored.

It was a peaceful afternoon. The detective agency of the great detective Al Funobori was the picture of tranquility. Al was slumped lazily on the sofa in the empty guest area, while his assistant, Rai Sunohara, brewed tea in the kitchen. Soft sunlight streamed through the window, and a cat was yawning on a nearby wall.
