(The first few chapters are set in the continuities of the 1960s TV serieses of Batman and Star Trek).

Captain James T Kirk spoke into his official log recording device: "Captain's Log Incremental. As our last attempt to make routine observations of 20th Century Earth was side tracked by the presence of Gary Seven and a new adventure, we briefly returned to the 23rd Century to check that history remained unaltered, and are now once again in orbit around earth in the late 1960s. I am about to lead an away team down to the surface of the planet in order to observe ancient policing methods, in the hope that some of them can be applied to the rest of our five year mission in space."

"Captain, wouldn't it be wise to leave Mr Spock in command of the ship," said Doctor McCoy, "His Vulcan ears are a little hard to explain to 1969 earthlings."

"You read my mind, Doctor," said Kirk.

"I thought that was one of his talents," said McCoy.

"Correction Doctor. I can only share another's thoughts when engaging in the Vulcan mind meld, which requires physical contact. To suggest that I could read the Captain's thoughts under other circumstances is to defy logic."

"Never mind, Mr Spock," said Kirk, "You have the conn. Sulu and Uhura will man the bridge. Bones, you can stay up here, if you're not needed in sick bay. Mr Chekov, you're with the away team. Scotty, select two security officers and have them meet us in the transporter room. Chekov, have the computer make ready civilian circa 1969 American police officer uniforms for all five of us. Phasers to be concealed in belt holsters unless I give the order to fire, and are to be set on stun only. We can't take the chance of taking a life in the past and upsetting history, no matter what we encounter down there."

Shortly after that, Kirk, Scotty, Chekov and two security staff named Marj and Nelson beamed down and materialized in an alley behind a large building. They walked around to the front and read its signage.

GOTHAM CENTRAL POLICE

"Well done Mr Kyle," said Kirk, aware that his transporter chief would not actually hear the congratulation, "Well gentlemen, we look the part. Let's go up and see what's up there. You know, I feel right at home in this black police uniform. I'm sure I could wear it for five years' straight if I'd been a police officer in this century."

"Aye, so long as you earned your hooks first," said Scotty.

They entered the building elevator and made their way to Commissioner Gordon's office.

"I don't believe I've met any of you officers," said Commissioner James Gordon, "But a man in my position is terribly busy. I'm sure you're all fine officers."

The phone rang, and Bonnie switched it through to the office. While Gordon was greeting Kirk and the others, Chief O'Hara took the call, and then hung up.

"Begorra, Commissioner! We've just had a report that Mr Freeze is robbing citizens of all their costume jewellery in Gotham Central Park, threatening to freeze anyone who resists."

"There's only one man who can handle Mr Freeze," said Commissioner Gordon, reaching for the red phone.

Elsewhere in Bruce Wayne's study at stately Wayne Manor, the red phone hotline began to beep. Alfred the Butler, who seemed to be perpetually dusting various objects within earshot of the Bat-phone, promptly answered the call.

"I'll summon him, Sir," said Alfred.

In the Wayne dining room, Aunt Harriet, Bruce Wayne and Dick Grayson were enjoying one of Alfred's home made beef stews.

"It's the phone in your study, Sir," said Alfred, entering the room.

Seeing that he would need to leave the table too, Dick began to speak.

"I… think I'd better head for the little ward's room," said Dick, "I'm not 100% sure that this particular beef stew agrees with me."

"Mercy alive, is no-one going to remain at the table," said Aunt Harriet, "Alfred, you might as well put the television on. If I can't enjoy lunch, I might as well catch the midday news update."

"Very well, Madam," said Alfred, and switched the set on, where it turned out the Mr Freeze robbery was the subject of the latest news update.

"Oh my," said Aunt Harriet, "Gotham has so many super criminals, that Batman never seems to get a respite. Something really should be done about it."

She got up, walked across the room, bumped a cabinet and then was hit on the head by one of Bruce's artifacts in his antiques collection, as it fell of the top of the cabinet. Once she'd passed out on the floor, it became evident to Alfred that for once it would be easier to conceal Batman's and Robin's departure.

Bruce and Dick entered the study.

"Yes Commissioner," said Bruce, picking up the Bat-phone.

"Cold news, Batman," said Commissioner Gordon, "Mr Freeze has returned to commit a series of robberies at freeze gun point in Gotham Central Park. I've got five new officers on call right now, but I daren't send them out inexperienced against such a formidable foe."

"Your professional discretion is held in high regard as always, Commissioner. Robin and I are on our way. To save time, we'll head straight to the park instead of meeting you in your office first," said Bruce and hung up the phone.

"Mr Freeze again! This is the first time he's struck since we met Batgirl. I sure hope she doesn't wind up frozen too."

"Not if we give him the cold shoulder first," said Bruce, "To the Bat-poles."

Bruce and Dick slid down into the Batcave, climbed into the Batmobile and roared out towards Gotham Central Park.
