WOULD
Jack Crawford would be delighted with the letter and so would the postal authorities and the lab. It was here she came on her first FBI assignment, when she was still a trainee, still believed everything, still thought that if you could do the job, if you could cut it, you would be accepted, regardless of race, creed, color, national origin or whether or not you were a good old boy. La Nazione would be pleased to have hounded him to death. He assumed the call would be traced. The man could disappear too well, and Pazzi would be left with nothing. Lecter would be sustained on a saline drip overnight, awaiting the next course. The first course would be prepared at table, and accordingly he organized his alcohol burners, with his copper fait-tout, his saucepan and sauté pan, his condiments and his autopsy saw. Privet Drive looked exactly as a respectable suburban street would be expected to look in the early hours of Saturday morning. Every now and then, sparks would fly out of the end of a skrewt, and with a small phut, it would be propelled forward several inches. "My dear Madame Maxime, if you have an alternative, I would be delighted to hear it."

Harry, would be questioned about Sirius's whereabouts. Reluctant though he was to accept more favors from Cedric, he also decided to use the prefects' bathroom; far fewer people were allowed in there, so it was much less likely that he would be disturbed. Harry would be forewarned if somebody was approaching the bathroom.
She told me that the Triwizard Tournament would be played at Hogwarts this year. He was dreading the Leaving Feast, which was usually a cause for celebration, when the winner of the Inter-House Championship would be announced. Carlo had told Rinaldo Pazzi he would commence with the beanbag gun, which was charged and ready, but if he got a chance to put the hypodermic anywhere in Dr Lecter's buttocks or legs, the beanbag would not be needed. It contains a number of preparations that would not be found in the general dispensary downstairs, the powerful sedatives and exotic sedative- hypnotics that make possible open-heart surgery and brain surgery on an aware and responsive patient. Then he said, Wormtail wouldn't be fed to the snake -- there was a snake beside his chair.

MUST
His arrangements had long been made, but now the alert must be given. It must be said that 911 got all but one digit of the false license plate right. Describe, with examples, the ways in which Transforming Spells must be adapted when performing Cross-Species Switches. Hagrid is providing a number of creatures...then there will be spells that must be broken...all that sort of thing, you know. Come, the niceties must be observed...Dumbledore would like you to show manners...Bow to death, Harry... All those that we can persuade of the truth must be notified immediately, and he is well placed to contact those at the Ministry who are not as shortsighted as Cornelius. "There is somebody else who must be mentioned in connection with Cedric's death," Dumbledore went on. "I am talking, of course, about Harry Potter."

COULD
The police left the noose in place until it could be fingerprinted, and then cut the stout electrical cord in the center of the noose to preserve the integrity of the knot.
THE BEAUTY of the pneumatic rifle was that it could be fired with the muzzle inside the van without deafening everyone around it - there was no need to stick the muzzle out the window where the public could see it. Cordell rigged slip-knot tourniquets just above each knee with cords that could be pulled behind the fence to keep the doctor from bleeding to death. There were no wipe marks on the bullets from a silencer, but a silencer could not be ruled out. Krendler could not be insulted when his interests were at stake. Finally, when the sun had risen, when his bedroom walls had turned gold, and when sounds of movement could be heard from Uncle Vernon and Aunt Petunia's room, Harry cleared his desk of crumpled pieces of parchment and reread his finished letter. Grinning faces could be seen under those that had their flaps open. It could have been handled better. You could have been killed.
