Thank you Mamyalynne... that makes the other one UNIT ... greenwich university + t (time) i think!

[Mamyalynne]

Ah yes, and a single person - a unit.

Well done.

[pomona]

... i meant T(ticket's terminal) of course...rushing, rushing...!

Pomona, if it helps, 23A is ???BE.

[vetuste_ennemi]

13A Uni+...t
It looks like SLUMBER because 23A is LET BE and 17D needs the T.

[vetuste_ennemi]

But can't parse it.

[pomona]

Thank you ...lumber is a synonym of prison so that works well

[Mamyalynne]

Didn't know that - so

Van (first) to Stop - S + Lumber.

thanks for the update.

[Davemano]

Slammer is slang for prison.

[vetuste_ennemi]

Bad news is that once originator and theme's location having been resolved some of us are still struggling with the small numbers bit. Life's a *** etc.

[Opsis]
