I finished the book, alas.
I find evidence that the book itself contemplates this may be the final P. D. James novel (I still hope not). Don’t read on if you don’t like folks spoiling endings. . . .
Adam Dagliesh does marry Emma. Kate gets back with her ex. Dagliesh contemplates whether this might be his last case. And one of the final scenes is that of an elderly lawyer, living in an upscale senior care facility who medidates on the end of life, age, and what it’s like.
Perhaps the pressure of this ending captures my imagination because I am at that point in life where I more and more find myself thinking about age, growing old. . . . . Clearly I am very much nearer the end of my life than the beginning. The pressure of the ending.
I can only hope for another Adam Dagliesh novel. In the meantime, I discovered that I missed a number of the earlier novels. So now I plan to begin again, keep the ending at bay in that way. . .
