Yes, there will be. J.K. Rowling has been quite engaged with this series and given its popularity, it's very likely she'll continue writing more Cormoran Strike novels.
As of now, there is no definite information regarding a new Cormoran Strike novel. The previous novels in the series have been well - received, which might suggest that there could be more in the future. But we have to consider that the author, J.K. Rowling, is involved in multiple projects. She might be exploring new ideas or working on other stories. The publishing world also plays a role. If the publishers see a high demand for a new Cormoran Strike novel and if J.K. Rowling has the time and inspiration, then it's very likely that we will see a new one. But until then, we can only wait and hope.
I don't think so. J.K. Rowling seems to be taking her time between novels in this series. And since there are no hints or news about a new one, we may have to wait a while.
The Cormoran Strike novels are generally published in a specific chronological order. The first one is 'The Cuckoo's Calling', followed by 'The Silkworm', 'Career of Evil', etc. Each novel builds on the previous one in terms of the development of the characters, especially Cormoran Strike and his assistant Robin Ellacott, and the overall mystery - solving plotline.
