This is not right, is it?

[Naughty Beef]

If you hadn't said anything, I wouldn't have noticed.

[Tdol]

It's right- you did say something and I did notice.

In fact, now that I think about it: "had have", whatever it is, is not the past perfect tense of "to have". The past perfect is formed from these two elements:

the past tense of "to have", which is "had";
the past participle of the main verb.

The past participle of "to have" is also "had", giving "had had", thus: "If you had not had said", which I have never heard a native speaker say. I can't think of any tense formed with "to have" plus the basic form of the main verb.

Spenser's book gives the only possible correct version.

You're right. I was careless. It should have been "had had" of course
