Phi is back to his usual day, but for how long? Were his recent perambulations the sign of something regular? Perhaps Friday, being a random day, is just one of the days he visits.
Anyway, this was what you expect from Phi: things don’t work out instantly (apart from one or two, like 5dn or 8dn) but you know that in due course all will become clear. I found this to be easier than is usual for Phi, but none the worse for that.
