How would I make camera manipulation create a shift lock kinda feel?

Okay so I have a sword fighting game, and the problem is that it's third person only which is fine, but when trying to fight and you end up just spinning in circles trying to hit your enemy, its kinda annoying. What I want to do, is make the camera be fixed onto the enemy's character, but still above your head, so you can see both yourself and the enemy and you are kinda in this shift lock state almost.

tl;dr - need camera to be fixed onto enemys character while still staying above my head

Any way I could do this? No code or anything just some kinda of explanation.

A small sample of code, This didn't really work.

if Key.KeyCode == Enum.KeyCode.Z and Equipped == true and Mouse.Target ~= nil and Mouse.Target.Parent:FindFirstChild("HumanoidRootPart") then
        workspace.CurrentCamera.CameraType = Enum.CameraType.Watch
        workspace.CurrentCamera.CFrame = Mouse.Target.Parent.Head.CFrame
    end
