Well i guess it is just theoretical but dock at 6:30 ( no clue as to staff disembark say 7:30-8 ) transport to london ( again may have had a car parked up somewhere close(more likely), could have caught train and tube, 1-2 hours max, has time enough to do the deed just need to think it through, could have been the mr kipper phone call but used a bogus sturgis address far enough if anyone work related was nearby, may also have known no stevenage road viewing happening so good address to meet (wm could be wrong timing 12:45 - 2-45 still the 45 but 2 hours out on her recall, then that makes her seeing sjl driving up fulham palace road work and the dodgy driving seen by the van driver just before so sjl under duress but trying to keep sw happy, so that gives sw from say 1:00 until 2:30 to get sjl to drive somewhere nearby but quiet do yhe deed and leave yhe car back at 123 sr closes down the possible location but would have to look at sw’s later crimes to see the sort of locations left, all dependent on weather sw left the qe2, i onow it was checked to see if he left but hey he is a cunning multiple murderer i am sure he could have left the ship and got back on without too much effort.
