1D Having the enemy in to complete a quartet (4,11) From the letters I already have the answer appears to be
( four dimensional.) Can see the quartet but the enemy in !! Could someone offer an explanation please. Thanks in advance.
I am a little puzzled by this one too. The only thought I had is that time is the 4th dimension, and the saying time is the enemy. If that's actually the explanation, I don't think it's a great clue.
