Diana Decker certainly exists (or existed), but what about dph. I know that there are many out there who believe that dph is a figment of my imagination. You will recall that almost two years ago I announced that the services of dph had been acquired as one of the contributors to this blog and since then, nothing has been heard of the legendary raconteur, guitarist and Professor of Protein and Nucleic Acid Biochemistry. However, I now of photographic proof of his existence. The picture was taken at his 50th birthday party on Saturday as he explained his latest research project to me. He has far too many friends and therefore there were far too many people at the party. But perhaps they also turned up simply to see whether he exists or not.
