Key Discussion Points and Episode Flow

1. Case Assignment and Grandma’s Modus Operandi

• [03:01–08:04]

  • Joe Friday and Ben Romero are assigned to "Grandma," an elusive check forger.
  • Grandma operates methodically: only three months a year (April, October, December).
  • She always uses personal checks, in amounts between $2 and $100.
  • Over nine years, she’s passed 1,273 checks totaling over $22,000.
  • Known for her ability to charm merchants and her ever-changing appearance.

  Quote:
  “Her apparent fine sense of timing and her knowledge of psychology was far and away superior to that of the ordinary paper hanger. If the file on Grandma was any indication, she apparently had been born to be a successful check forger.” — Joe Friday ([08:04])

2. Investigative Difficulties

• [08:05–13:47]

  • Merchants across the city are warned and stakeouts double.
  • Description of Grandma varies; clerks often say she "reminded them of their mother."
  • The detectives are repeatedly stumped as she switches up her tactics but maintains her disarming persona.

  Quote:
  “One thing sure. Her timing's just as good as it was nine years ago. Downtown Merchants Association screaming again. They're looking for action. So are we.” — Ben Romero ([09:23])

  • The team interviews a store owner, who describes Grandma as “just as homey as you please... a real good sport. Joshing all the time. Fine personality.” — Store Owner ([12:42])

3. Pattern Recognition and Preparation

• [13:48–16:40]
  • After another “season” of forgeries, the detectives prepare for her October return.
  • A revised description and MO are widely circulated.
  • As anticipated, forgeries resume right on schedule.

4. The Break in the Case: A Mistake

• [17:41–21:24]
  • Grandma slips by using the real identity of Mary Walker, including her charge plate, to cash checks.
  • Friday and Romero interview Mary Walker, who reports her charge plate missing after a local club meeting.
  • The club’s attendance book, signed by all present, offers a critical lead.

5. Unmasking the Suspect

• [21:25–24:03]
  • Police handwriting analysis: signature of one "Mrs. Inez Lambert" at the club matches Grandma’s known signatures.
  • Inez Lambert: well-respected, highly charitable, with a reputation "spotless."
  • Her annual charitable donations far exceed her legitimate household income, suspiciously matching the amounts from the forgeries.

6. Confrontation and Confession

• [24:04–29:18]

  • Friday and Romero confront Mrs. Lambert at home.
  • The tension is heightened by her calm, domestic multitasking—preparing a dessert while under questioning, denying involvement.

  Quote:
  “That's a silly thing for you to say, Sergeant. I told you, I have my own charge plate. I never borrow anyone else's.” — Inez Lambert ([25:14])

  • Slowly, the evidence presses in: handwriting, plate possession, patterns in her living and giving.
  • Lambert ultimately confesses: her forgeries were all to fund extensive charitable works.

  Quote:
  “It was all for charity. There were so many of them... Orphanages, Old People's Home, Christmas Poor Fund. And then the overseas relief charities. They all need money. Somebody has to take care of them.” — Inez Lambert ([28:29])

  • She asks Friday if the Lord would think her wrong for helping the poor by such means.

  • Friday’s reply is as wry as it is direct:

    Quote:
    “He didn't use a checkbook.” — Joe Friday ([29:17])

7. Resolution

• [29:19–End]
  • The trial result: Inez Lorraine Lambert pleads guilty to two counts of forgery; the court sentences her as prescribed by law.
  • The theme of police efficiency and diligence is reinforced as the episode concludes.

Notable Quotes & Moments

• On Grandma’s Elusiveness:
  “Nine years. That's a long streak of luck for any paper hanger. That's just it. This old gal's not just an ordinary paper hanger. She's no amateur, don't get me wrong. But she doesn't operate like any check forger I've ever known.” — Ferguson ([06:00])

• On the Human Element:
  "She was a nice, charming little lady, about 55 or 60… She reminded him of his mother." — Fergie, quoting a clerk ([09:10])
