[EX Q]: CHAPTER XXVII. LEONARD DE CARTIENNE. 

We all three stood and looked at one another for a moment, Milly Hart with her finger still pointing to the vacant place where the photograph had been. Then Cecil broke into a short laugh. 

"We're looking very tragical about it," he said lightly. "Mysterious joint disappearance of Leonard de Cartienne and a photograph of Mr. Hart. Now, if it had been a photograph of a pretty girl instead of a middle-aged man, we might have connected the two. Hallo!" 

He broke off in his speech and turned round. Standing in the doorway, looking at us, was Leonard de Cartienne, with a slight smile on his thin lips. 

"Behold the missing link--I mean man!" exclaimed Cecil. "Good old Leonard! Do you know, you gave us quite a fright. We expected to find you here and the room was empty. Are you better?" 

"Yes, thanks! I'm all right now," he answered. "I've been out in the yard and had a blow. What's Milly looking so scared about? And what was it I heard you say about a photograph?" 

"Father's likeness has gone," she explained, turning round with tears in her eyes. "It was there on the mantelpiece this afternoon and now, when we came in to look at it, it has gone!" 

"I should think that, if it really has disappeared," de Cartienne remarked incredulously, "the servant must have moved it. Ask her." 

Miss Hart rang the bell and in the meantime we looked about the room. It was all in vain. We could find no trace of it, nor could the servant who answered the summons give us any information. She had seen it in its usual place early in the morning when she had been dusting. Since then she had not entered the room.

[EX Q]: Oakland is the largest city and the county seat of Alameda County, California, United States. A major West Coast port city, Oakland is the largest city in the East Bay region of the San Francisco Bay Area, the third largest city overall in the San Francisco Bay Area, the eighth largest city in California, and the 45th largest city in the United States, with a population of 419,267 . It serves as a trade center for the San Francisco Bay Area; its Port of Oakland is the busiest port in the San Francisco Bay, the entirety of Northern California, and the fifth busiest in the United States of America. The city was incorporated in 1852. 

Oakland's territory covers what was once a mosaic of California coastal terrace prairie, oak woodland, and north coastal scrub. Its land served as a rich resource when its hillside oak and redwood timber were logged to build San Francisco, and Oakland's fertile flatland soils helped it become a prolific agricultural region. In the late 1860s, Oakland was selected as the western terminal of the Transcontinental Railroad. Following the 1906 San Francisco earthquake, many San Francisco citizens moved to Oakland, enlarging the city's population, increasing its housing stock and improving its infrastructure. It continued to grow in the 20th century with its busy port, shipyards, and a thriving automobile manufacturing industry.

[EX Q]: A man has been charged with a federal hate crime in connection with what authorities say was a racially motivated "knockout" assault against an elderly black man, the U.S. Justice Department said Thursday. 

Conrad Alvin Barrett, 27, of Katy, Texas, has been charged with one count of violating the Matthew Shepard and James Byrd Jr. Hate Crimes Prevention Act. 

According to the federal complaint, Barrett attacked the 79-year-old man "because of the man's race and color." He will next appear in court Friday afternoon for a detention hearing. 

The suspect made a video of the attack November 24, the complaint said. In the video, he allegedly commented that "the plan is to see if I were to hit a black person, would this be nationally televised?" 

He then allegedly "hit the man with such force that the man immediately fell to the ground. Barrett then laughed and said 'knockout,' as he ran to his vehicle and fled." 

The victim suffered two jaw fractures and was hospitalized for several days, the complaint said. 

Barrett's attorney, George Parnham, told CNN the affidavit does not "pull back the layers of mental health." 

His client has bipolar disorder and takes medication, Parnham said in an earlier call. 

Parnham said he could not state whether his client carried out the attack, but, "mental health issues definitely played a part in anything that occurred." 

Barrett "is very sorry for this person," Parnham said, adding that he and his client haven't had much opportunity to discuss the facts of the case.
