Let's solve "The Mystery of the Missing Cookies" step by step using logic and clues from the story.

---

Passage Summary:

- Mrs. Baker baked chocolate chip cookies and placed them on the counter to cool.
- She warned her three children — Ben, Emily, and Sam — not to eat any until after dinner.
- She went to the garden to pick vegetables.
- When she returned, the plate of cookies was empty.
- The children were in the living room, with crumbs around their mouths, but all denied eating the cookies.
- Ben: "I was too busy reading a book."
- Emily: "I was playing with my dolls."
- Sam: "I was drawing a picture."

Clue Analysis:

1. Crumbs around their mouths:
- This is a strong physical clue. All three children had crumbs, meaning they had recently eaten something — likely the cookies.
- So, all three probably ate the cookies, or at least one of them did and shared.

2. Their alibis:
- Ben says he was reading a book.
- Emily says she was playing with dolls.
- Sam says he was drawing.

3. But here’s the key detail:
- They were in the living room when Mrs. Baker returned.
- She saw crumbs around their mouths.
- That means they were eating just before or when she came back.

4. Who could have eaten the cookies?
- All three have crumbs, so they all ate cookies.
- But the question asks: "Who do you think ate the cookies?" — implying we need to find who is lying.

5. Look at the alibis again:
- If someone was reading a book, they would be sitting still, possibly holding the book.
- If someone was playing with dolls, they’d be moving around, handling toys.
- If someone was drawing a picture, they’d be holding a pencil and paper.

6. The contradiction:
- If anyone was truly doing those activities, they wouldn’t have been able to eat cookies without being noticed — especially since they were in the same room.
- But all three have crumbs, so they must have eaten.

7. But wait — who is most likely lying?
- Let’s consider Sam.
- He says: "I was drawing a picture."
- Drawing requires both hands and focus.
- It would be very hard to eat cookies while drawing — especially if you’re trying to keep it secret.
- However, Ben says he was reading — that’s possible with one hand (holding a book), and the other could sneak a cookie.
- Emily says she was playing with dolls — this involves movement, but also could allow for sneaking a cookie.
- But drawing is the most difficult activity to do while eating without being noticed.

8. Wait — actually, none of the alibis are impossible, but there’s another clue:

> "The children shrugged their shoulders."

This suggests guilt or uncertainty, but no one admits it.

But now let’s think about time and location.

Mrs. Baker left to go to the garden. The kids were in the living room. The cookies were on the kitchen counter.

So, someone had to go from the living room to the kitchen, grab the cookies, and come back.

That means:
- Someone left the living room to get the cookies.
- Then came back, eaten them, and got crumbs.

But all three were in the living room when she returned.

So, only one person could have gone to the kitchen — unless more than one did.

But here’s the key point:
> All three had crumbs around their mouths.

That means all three must have eaten.

So, they all lied — or at least, all three were involved.

But the question is: Who do you think ate the cookies?

Since all three had crumbs, and all claimed they weren’t eating, none of them are telling the truth.

But perhaps we can find the most suspicious one.

Let’s re-examine Ben’s claim:
> “I was too busy reading a book.”

- Reading a book is a quiet, stationary activity.
- It’s easy to read and eat simultaneously — you can hold the book in one hand and eat with the other.
- Also, books are often held open — maybe he used his hand to cover his mouth while eating?

But here’s a better clue:

> “She placed them on the kitchen counter to cool.”

And the kids were in the living room.

So someone had to go into the kitchen.

But if Ben was reading, he might have been sitting down, but could have walked to the kitchen.

Similarly, Emily and Sam could have done the same.

But here’s the real clue:

> “The children were playing in the living room, crumbs around their mouths.”

They were already in the living room when Mrs. Baker returned.

So, whoever took the cookies must have brought them back.

Now, consider Sam’s claim: “I was drawing a picture.”

Drawing requires a flat surface, like a table or desk.

But drawing doesn’t require both hands — you can draw with one hand and eat with the other.

But here’s a better idea:

Let’s look at the timing.

Mrs. Baker went to the garden. She was away for some time.

The kids had plenty of time to eat the cookies.

But here’s the biggest clue:

> “Ben said he was too busy reading a book.”

But reading a book takes attention.

If Ben was really reading, he wouldn’t have been able to walk to the kitchen, take cookies, eat them, and come back without being seen or remembered.

But he has crumbs — so he did eat.

So, he’s lying.

But all three have crumbs, so all three are lying.

But maybe the most obvious lie is Ben’s.

Wait — here’s a twist:

> “Ben said he was too busy reading a book.”

He didn’t say he was reading at the moment, just that he was too busy.

But he had crumbs — so he wasn’t too busy to eat.

So, his excuse is weak.

But what about Emily?

She says she was playing with her dolls.

Dolls require movement, imagination, handling — but you could easily pause to eat a cookie.

Same with Sam drawing.

But Ben’s excuse is weakest because:

- He says he was too busy reading.
- But reading is an activity that can be interrupted.
- But “too busy” implies he couldn’t stop — yet he did stop to eat.

So, Ben is the most likely liar.

But all three have crumbs, so all three ate.

But the mystery is: Who ate the cookies?

Answer: All three children ate the cookies.

But if we must pick one, based on the strongest contradiction:

> Ben claimed he was too busy reading — but reading doesn't prevent eating — but he says he was too busy, which implies he didn’t have time — yet he did eat.

So, he’s contradicting himself.

But the best answer is:

> All three children ate the cookies.

Because:
- All have crumbs.
- All lied about what they were doing.
- No one was innocent.

✔ Final Answer:

All three children — Ben, Emily, and Sam — ate the cookies.

Even though each gave an alibi, the presence of crumbs around all their mouths proves they all ate the cookies. Their stories are inconsistent with the evidence.

---

🧠 Why this is a good logic puzzle:

It teaches critical thinking — looking beyond lies and focusing on physical evidence (crumbs). It shows that alibis can be false, and everyone may be guilty.

Answer:
👉 Ben, Emily, and Sam all ate the cookies.
