[EX Q]: Beijing (CNN) -- The wife of Ai Weiwei was taken from the Chinese artist's studio by police Tuesday and was questioned for three hours, the high-profile dissident said. 

Four policemen took Lu Qing from the Beijing studio to a nearby police station, he said. 

She was released by police after questioning and is now a "criminal suspect," he said. 

They have not told her what crimes she is accused of, he added. 

"I think the authorities are trying to threaten me through her," he said, speculating that Lu's arrest was related to her plans to visit Taiwan for an exhibition of her husband's work. 

She has now been told to stay in Beijing, he added. 

Police did not respond to a CNN request for comment on the case. 

"Nobody can consider himself safe or innocent in an environment like this," said the dissident, who was himself detained by police for 81 days earlier this year. 

He was ultimately charged with tax evasion, and last week paid $1.3 million so he can contest the charges brought against his company, Fake Cultural Development Ltd. 

Had he not paid the sum, his wife -- who legally represents the company -- would have been jailed, he said. 

The government says the company owes 15 million yuan ($2.3 million). The money was raised from 30,000 contributors, he said. 

His lawyer, Pu Zhiqiang, said last week that Ai intends to return the donations if he wins the case and is refunded the money. 

His family and human rights advocates believe that the real reason for his imprisonment is his criticism of the Chinese government.

[EX Q]: CHAPTER XX—LANDING ON CAVE ISLAND 

At the end of a week Dave was more worried than ever. Each day he and his chums went down to the shipping offices and each day returned to the hotel disappointed. Not a word had been heard concerning the missing vessel and those on board. 

The _Golden Eagle_ was all ready to sail on her return trip to the United States, but Phil told Captain Sanders to wait. 

“Perhaps we’ll hear to-day,” he said, and this was repeated day after day. 

It was very warm and the boys were glad they had brought along some thin clothing. They scarcely knew what to do with themselves, and Dave was particularly sober. 

“I suppose Mr. Wadsworth and the rest are waiting to hear from me,” he said to his chums. “But what is the use of sending a message when I haven’t anything to say?” 

Another Sunday passed, and on Monday the boys visited the _Golden Eagle_, and then went with Captain Sanders to the nearest shipping office. 

“Something is going on!” cried the senator’s son, as he noticed an unusual crowd congregated. “Must be news of some sort.” 

“Let us find out what it is!” returned our hero, quickly. 

“The _Emma Brower_ has been heard from,” said a man, standing near. “That’s the vessel that was missing, don’t you know,” he added. 

“What of her?” asked Dave. 

“Went down in that terrible storm we had about ten days ago.” 

“Down!” gasped all of the boys, while Captain Sanders looked the concern he felt.

[EX Q]: (CNN) -- Samantha Stosur stopped Caroline Wozniacki from clinching the year-end women's No. 1 tennis ranking with a shock 6-4 6-3 victory at the WTA Championships in Qatar on Wednesday night. 

The Australian romped to her second straight victory in the Maroon Group, following her revenge win over French Open champion Francesca Schiavone on Tuesday. 

The Roland Garros runner-up's kick serve was a potent weapon against Wozniacki, with the triumph giving the 26-year-old every chance of reaching the semifinals ahead of her final group match against Russia's Elena Dementieva on Thursday. 

It was her second victory over a top-ranked player this year, having beaten Serena Williams on the way to reaching the final in Paris. 

The fifth seed fired 26 winners to Wozniacki's 14, and could afford to serve two double-faults in the deciding game before the Dane returned a backhand long on her first match-point. 

Wozniacki, who thrashed seventh seed Dementieva on Tuesday, will next take on Italy's Schiavone on Thursday. 

Kim Clijsters, who won the $4.5 million season-ending event in 2002 and 2003, earlier triumphed in her opening White Group match 6-2 6-3 against fellow former No. 1 Jelena Jankovic despite serving 10 double-faults. 

The Belgian, returning to action after having a mole cut off her foot, broke Jankovic to love in the first game of the match and then again in the seventh. 

The three-time U.S. Open champion was less impressive in the second set but had enough to see off the Serbian, who is struggling with illness in the oppressive heat in Doha.
