One step at a time. Stop whenever you like and finish it yourself. xoxo, Mae
Step 1 of 8Book: step 1
Read the reasons first. Can you see who goes where?
Daisy → F7
○ placed✕ ruled out (for whom: the letter)▢ look here⊙ still possible
- Daisy said: “She was in row 7, beside a tall shelf.” Only one square on the whole plan fits that: F7. So she stood there.
Step 2 of 8Book: step 2
Read the reasons first. Can you see who goes where?
Marcus → G3
○ placed✕ ruled out (for whom: the letter)▢ look here⊙ still possible
- Look at row 2. Every row holds exactly one person, and only Bernard can still stand in row 2 (A2, B2, C2, D2, E2 or G2). So Bernard must be in row 2, even though his clue allows other squares. All his other squares are out.
- Look at row 3: nobody stands in row 3 yet. Who can still go there? Only Marcus: everyone else either has it crossed out or is kept away by their own clue. Marcus's only square in row 3 is G3, so he stood there.
Step 3 of 8Book: step 3
Read the reasons first. Can you see who goes where?
Gus → A1
○ placed✕ ruled out (for whom: the letter)▢ look here⊙ still possible
- Gus said: “He was in a corner of the floor plan.” That fits A1, G1 and A7. A7 is in row 7, where Daisy already stands. G1 is in column G, where Marcus already stands. One square is left: A1. So Gus stood there.
Step 4 of 8Book: step 4
Read the reasons first. Can you see who goes where?
Ned → B5
○ placed✕ ruled out (for whom: the letter)▢ look here⊙ still possible
- Look at row 4. Every row holds exactly one person, and only Pearl can still stand in row 4 (D4 or E4). So Pearl must be in row 4, even though her clue allows other squares. Pearl can't be at C5 or E5 any more.
- Look at row 5: nobody stands in row 5 yet. Who can still go there? Only Ned: everyone else either has it crossed out or is kept away by their own clue. Ned's only square in row 5 is B5, so he stood there.
Step 5 of 8Book: step 5
Read the reasons first. Can you see who goes where?
Bernard → E2
○ placed✕ ruled out (for whom: the letter)▢ look here⊙ still possible
- Rule 3: the victim's room holds exactly two people, the victim and the murderer. So Bernard needs a square where exactly one other person can join him. At C2 or D2, nobody could join him: nobody else can still stand in the Front Desk. So Bernard can't be at C2 or D2.
- Bernard is the victim: his card gives no square, only Rule 3. Rows 1, 3, 5 and 7 and columns A, B, F and G already have their person, so those squares are crossed out. C2 and D2 were ruled out above. D4, E4, C6, D6 and E6 were ruled out in step 2. One square is left: E2. So Bernard stood there.
Step 6 of 8Book: step 6
Read the reasons first. Can you see who goes where?
Pearl → D4
○ placed✕ ruled out (for whom: the letter)▢ look here⊙ still possible
- Pearl said: “She was in a room with a book basket, but not beside one.” That fits D4, E4, C5 and E5. C5 and E5 are in row 5, where Ned already stands. E4 is in column E, where Bernard already stands. One square is left: D4. So Pearl stood there.
Step 7 of 8Book: step 7
Read the reasons first. Can you see who goes where?
Theo → C6
○ placed✕ ruled out (for whom: the letter)▢ look here⊙ still possible
- Theo said: “He was in the Cafe.” That fits B6, C6, D6, C7 and D7. C7 and D7 are in row 7, where Daisy already stands. B6 is in column B, where Ned already stands. D6 is in column D, where Pearl already stands. One square is left: C6. So Theo stood there.
Step 8 of 8
Case closed!
Everyone is placed. Rule 3: the victim's room holds exactly two people, the victim and the murderer. Who shares the Kids Books with Bernard? Only Marcus.
