This is the fourth story in the comedy series featuring Canadian superspies Agent Diamond and Charming Guy. In this tale, Agent Diamond is pressed into catsitting an extremely difficult cat, and manages to solve a crime while doing so. This story was written and dedicated to a donor as a reward for a crowdfunding campaign I conducted in 2014, aiming at raising funds for a cancer research project. The work for the project is still ongoing, and I am grateful to all donors for their assistance.
