half a pump

I never found the hole in the inner tube (swapped for spare), or any
foreign body in the tyre either.

Sounds like someone let the tyre down and took the pump apart so you
couldn't pump it back up.

OK - in daylight, with a sink of water, I've found the pinprick hole.

Unlikely. The bike is chained to railings in line of sight of the
security guard at the reception desk. There was a significant amount
of crud up the barrel of the pump, and around the threads. The cap was
still on the valve. None of the other fittings on the bike had been
fiddled with, especially the dual halogen headlight I mentioned here
previously[1], which is too fiddly, and the connectors too fragile, to
remove from the bike on a regular basis.

I previously mounted the pump with the nozzles pointing up and at the
top of the down tube to try and keep them away from the crud. Now I'm
going to mount it the other way round, so if the plunger and handle
assembly do work loose, they are less likely to drop out.
