Those of you with kids will be familiar with the elusive "Where's Wally".
But the Chief Executive of the East of England Strategic Health Authority, Neil McKay, seems similarly elusive. For some nine months, consultants at Bedford Hospital have been trying to arrange to meet him, but every time a date is agreed, it is then suddenly cancelled.
Rumours are now circulating at the hospital that perhaps he doesn't exist at all. So if anyone does manage to spot the elusive Neil, please let us know.
