I added the word "suicide" to describe what I needed the workbook to do. Apparently that was the magic word for Google. I found this and it works.

With ThisWorkbook
.Saved = True
.ChangeFileAccess xlReadOnly
Kill .FullName
.Close False
End With
This wipes out the workbook completely. It bypasses the Recycle Bin. I have a lot of copies of my test file.
