Q: (CNN) -- An Arizona couple who wanted to adopt a woman's baby know more than they're saying about the 8-month-old boy's disappearance, police say.

Gabriel Johnson hasn't been seen since December 26, police said, and his mother was arrested last week in Miami Beach, Florida, after not reporting for a December 28 child custody hearing in Arizona.

"We have some good indications at this point with our investigation that Tammi and Jack Smith do know more information than they have provided to us that could possibly lead us to Gabriel," Sgt. Steve Carbajal, spokesman for the Tempe (Arizona) Police Department, told HLN's Nancy Grace on Thursday.

For their part, the Smiths told HLN's Jean Casarez on "Nancy Grace" that they voluntarily took polygraph tests Friday at the Tempe Police Department.

"The polygraph test is not like what you see on TV," Jack Smith said. "It's almost like being strapped into the electric chair, so it's very intensive. And we were very happy to do it."

The Smiths have said they met Elizabeth Johnson, 23, seven months ago during a long layover at an airport, and later the three discussed a plan to adopt Johnson's child, Gabriel.

But the boy's father, Logan McQueary, has legal custody and has said Elizabeth Johnson urged him to sign papers giving the Smiths custody of the boy, but he refused.

"She didn't want Logan to have the baby, and we couldn't adopt the baby because Logan wouldn't sign the papers," Tammi Smith said on "Nancy Grace."

Q: CHAPTER XXVIII

TWO OF THEM

When Tommy started impulsively on what proved to be his only Continental trip he had expected to join Mrs. Jerry and her stepdaughter at Bad-Platten. They had been there for a fortnight, and "the place is a dream," Mrs. Jerry had said in the letter pressing him to come; but it was at St. Gian that she met the diligence and told him to descend. Bad-Platten, she explained, was a horror.

Her fuller explanation was that she was becoming known there as the round lady.

"Now, am I as round as all that?" she said plaintively to Tommy.

"Mrs. Jerry," he replied, with emotion, "you must not ask me what I think of you." He always treated her with extraordinary respect and chivalry now, and it awed her.

She had looked too, too round because she was in the company of Lady Pippinworth. Everyone seemed to be too round or too large by the side of that gifted lady, who somehow never looked too thin. She knew her power. When there were women in the room whom she disliked she merely went and stood beside them. In the gyrations of the dance the onlooker would momentarily lose sight of her; she came and went like a blinking candle. Men could not dance with her without its being said that they were getting stout. There is nothing they dislike so much, yet they did dance with her. Tommy, having some slight reason, was particularly sensitive about references to his figure, yet it was Lady Pippinworth who had drawn him to Switzerland. What was her strange attraction?

Answer the following questions:
1. What place is a dream?
2. Who had said this?
3. to whom?
4. Were they to meet up?
5. Did she change her mind?
6. why?
7. why did she think so?
8. Who was with Mrs. Jerry?
9. was she round also?
10. Was she very thin?
11. How did Tommy feel about Mrs. Jerry?
12. how did she feel about this?
13. What was her step daughter's name?
14. Where men attracted to her?
15. What happened to them when they danced with her?
16. Did they like this?
17. Who brought Tommy to Switzerland?
18. Was Tommy sensitve about his figure?
19. How did Mrs. James communicate with Tommy?
