"By sunrise, Thomas was missing."
Grandma stared at the floor.
"The insurer's investigator claimed Thomas never arrived at their meeting place."
"Management told me to say nothing until the company could determine what had happened."
"I obeyed for twenty-four hours."
"Then forty-eight."
"Then longer."
Michael's voice broke slightly.
He paused.
Grandma did not comfort him.
She simply waited.
"When I finally decided to speak, the flight bag was gone."
"The storage record had been altered."
"The maintenance pages had disappeared."
"And the airline's official story was already moving in another direction."
Grandma's jaw tightened.
"What direction?"
Michael turned the page.
His face went tense.
"They suggested Thomas left voluntarily."
Grandma laughed once.
It was a terrible sound.
"I remember."
I looked at her.
"They told you that?"
"Not directly."
Her eyes stayed on Michael.
"They let people whisper it."
Michael continued.
"Evelyn, I knew Thomas would never abandon you."
Grandma covered her eyes with one hand.
"But I was afraid."
"I had a wife and two young children."
"I told myself I was protecting them."
"The truth is that I was protecting myself."
Michael lowered the page.
His face was wet now.
Grandma's remained still.
"Keep going."
He turned to the final page.
"Years later, I learned the insurer's investigator had kept a duplicate cassette."
"He placed it in a private safe-deposit box."
"Before I could obtain it, he became ill and his estate was sealed in a legal dispute."
"I spent years trying to locate the box."
Grandma leaned forward.
Michael read the final lines slowly.
"The key is connected to 34A."
"Thomas said Evelyn would understand when the time came."
"If she still has the wings, the number she needs is inside them."
Michael stopped.
Grandma looked at the opened pilot wings.
Inside the hollow backing, beneath where the film strip had been hidden, were four tiny engraved digits.
6-1-1-3.
I looked at Michael.
"Is that a safe-deposit box number?"
He shook his head.
"I don't know."
Grandma whispered, "I do."
We all looked at her.
She held the wings up to the cabin light.
"Thomas used four-number codes for dates."
"What date is 6-1-1-3?" I asked.
Her eyes moved to the old boarding pass.
"June eleventh."
She swallowed.
"The day he proposed to me."
Then she looked at Michael.
"And I know where he would have put the key."
Grandma asked Michael to read Patrick's letter again from the beginning.
This time she interrupted him whenever a date or name appeared.
She wanted details.
Exact dates.
Exact places.
Exact wording.
The emotional shock had become investigation.
That was how Grandma survived difficult things.
She organized them.
"October seventeenth," she said.
"Thomas called me at nine fourteen that night."
I looked at her.
"You remember the time?"
"I wrote it down."
"Why?"
"Because he sounded strange."
She described the call for the first time.
Grandpa had told her the flight was delayed.
He had said he might stay near the airport overnight.
Then, just before hanging up, he told her to make sure the silver wings were still on her purse.
She had laughed and asked why.
He had answered, "Because you lose everything except that purse."
Grandma had thought it was a joke.
Now nobody did.
Michael wrote down the time of the call.
"That was before my father's note says they met."
Grandma nodded.
"Then Thomas had already decided to hide something before Patrick became involved."
Michael looked at the wings.
"Which means the copy inside them may be older than the missing flight bag."
Grandma leaned back.
"Then maybe Thomas trusted me before he trusted anyone else."
Her voice was quiet.
But for the first time all day, there was comfort in it.
Chapter 7 - THE LOCKER AT UNION STATION
The rest of the flight felt longer than the entire day before it.
Grandma refused to move from 34A.
Michael offered to let her rest in first class.
She shook her head.
"I waited twenty-seven years to sit here."
"I'm staying until we land."
I moved to an empty seat nearby after the flight attendant quietly rearranged two passengers who were happy to trade for my first-class seat.
For the first time since boarding, Grandma told me the part of her marriage she had kept hidden.
Before Grandpa became a pilot, he and Grandma had taken a train across the country when they were young.
They had barely enough money for food.
At Los Angeles Union Station, Grandpa had asked her to marry him beside a row of old rental lockers.
He had no ring yet.
Instead, he slipped a brass locker key onto her finger and told her he would replace it with something better someday.
She had laughed so hard that a station employee threatened to throw them out.
The next morning, Grandpa bought a cheap silver ring from a pawn shop.
But Grandma kept the locker key.
"Where is it now?" I asked.
"In a box at home."
"Then how does that help us in California?"
Grandma looked at me.
"Because Thomas kept a second key."
"To the same locker?"
"Not the same physical locker."
"Then what?"
"A bank box opened years later under the nickname we used for that place."
Michael, listening from across the aisle, leaned closer.
"Union 34?"
Grandma looked at him.
"How did you know?"
He pointed to a line in Patrick's letter.
"My father wrote 'Union 34' in the margin."
Grandma exhaled slowly.
"Thomas loved codes that were obvious only after you knew the story."
I almost smiled.
"That sounds exhausting."
"It was."
For the first time that day, Grandma actually laughed.
The sound lasted only a second.
Then the seriousness returned.
When we landed in San Diego, two federal transportation investigators met us at the gate.
Michael had called ahead.
The senior investigator introduced herself as Lena Ortiz.
She was in her late forties, calm, direct, and careful with every word.
Her partner, Grant Ellis, carried a hard evidence case.
Grandma handed them the microfilm strip without hesitation.
She kept the wings.
Lena examined Patrick's letter and the old boarding pass.
"Mrs. Walsh, we can arrange secure transport to your hotel."
Grandma shook her head.
"I need to go to Los Angeles."
Lena blinked.
"Today?"
"Yes."
"That's a long drive."
