  1. Sandra's clue: She's in column F. 5 cells remain possible: F1, F2, F5, F6 and F7.
  2. Ivan's clue: He's right next to the Cloakroom and in the Security Room. It leaves a single cell: C4.
  3. Tariq's clue: He's in row 2. 7 cells remain possible.
  4. Javier's clue: He's 4 rows away from the Reception Area and 5 rows away from the Cloakroom. It leaves a single cell: D1.
  5. Lucy's clue: She's next to a window. 5 cells remain possible: C1, G1, E4, C6 and A7.
  6. Carla's clue: She's in a corner. 26 cells remain possible.
  7. The stolen item's clue: It's 6 columns away from the Inner Courtyard. It leaves a single cell: G6.
  8. Ivan can only be on C4. No one else can be in row 4 or column C, and no other character can be in the Security Room.
  9. Javier can only be on D1. No one else can be in row 1 or column D, and no other character can be in the Storage Room.
  10. C1, G1, E4 and C6 have already been ruled out, so Lucy can only be on A7. No one else can be in row 7 or column A, and no other character can be in the Cloakroom.
  11. The Egyptian Urn can only be on G6. No one else can be in row 6 or column G.
  12. There are as many suspects (counting the item) as rows, so each row holds exactly one. Only Carla can still reach row 3, so that is where she must be.
  13. Every other cell the clue allowed has already been ruled out, so Carla can only be on E3.
  14. There are as many suspects (counting the item) as rows, so each row holds exactly one. Only Sandra can still reach row 5, so that is where she must be.
  15. F1, F2, F6 and F7 have already been ruled out, so Sandra can only be on F5. No one else can be in row 5 or column F, and no other character can be in the Reception Area.
  16. A2, C2, D2, E2, F2 and G2 have already been ruled out, so Tariq can only be on B2.

Conclusion: Sandra is the only person sharing the Reception Area with the Egyptian Urn, which is on G6. She is the thief.
