Pooley shook his head. “We have been in Penge,” he said.

“Penge,” said Omally, nodding vigorously.

“Ah,” said Neville thoughtfully. “I haven’t actually been there myself, but I understand that it’s very nice.”

“Splendid,” said Pooley.

“Very nice indeed,” his colleague agreed. “You’d love it.”

Neville shrugged and turned away to cash up the traditional “No Sale” and extract for himself the price of a large scotch. As he did so Pooley remembered the Professor’s request.

“Could I have a pound’s worth of change while you’re at it?” he asked politely.

Neville froze in his tracks. A pound’s worth of change? So that was it, eh? The old “have one yourself, barman” was nothing more than the Judas kiss. Pooley planned to play the video machine. “You bastard!” screamed Neville, turning upon the drinker.

“Pardon me?” said Jim.

“Pound’s worth of change is it? Pound’s worth of change? You treacherous dog.”

“Come now,” said Jim, “steady on.”

“Steady on? Steady on? Have one yourself barman and a pound’s worth of change while you’re at it! What do you take me for?”

“Seemed a reasonable request to me.” Pooley looked towards Omally, who was covering his drink. “What is going on, John?” he asked.

Omally, who was certainly never one to be slow on the uptake, explained the situation. “I think that our good barman here believes that you want the money to play the video machine.”

Pooley, whose mind had been focused upon matters quite removed from video games, suddenly clicked. “Oh,” he said, “good idea, make it thirty-bobs’ worth, Neville.”

“AAAAAAGH!” went the part-time barman, reaching for his knobkerry.

Pooley saw the hand vanishing below counter level and knew it to be a very bad sign. “Come now,” he implored, backing away from the bar, “be reasonable. I haven’t played it in a week, I was just getting the hang of it. Look, let’s just say the quid’s-worth and call it quits.”

Neville brought the cudgel into prominence. “I’ve had enough,” he shouted, hefting it in a quivering fist. “You traitor. Touch the thing and you are barred, barred for life. Already today have I barred one regular, another will do no harm.”

“Who is the unhappy fellow?” asked Omally who, feeling himself to have no part in the present altercation, had not shifted from his seat.

“Norman,” growled Neville. “Out, barred for life, finished, gone!”

Omally did his best to remain calm. “Norman?”

“Norman.”

“Norman Hartnell of the corner shop?”

“That Norman, yes.”

“Norman Hartnell, the finest darts player this side of the Thames? Norman the captain of the Swan’s darts team? The five times trophy-winning darts team? The very darts team that plays at home for the championship on the twenty-ninth? That Norman you have barred for life?”

What colour had not already drained from Neville’s naturally anaemic face took this opportunity to make an exit via his carpet-slipper soles.

“I… I…” The barman rocked to and fro upon his heels; his good eye slowly ceased its ticking and became glazed, focused apparently upon some point far beyond the walls of the Swan. He had quite forgotten the darts tournament. The most important local sporting event of the entire calendar. Without Norman the team stood little hope of retaining the shield for a sixth year. What had he done? The locals would kill him. They would tar and feather him and ride him out of the town on a rail for this. Darts wasn’t just a game in Brentford, it was a religion, and the Flying Swan its high temple. A bead of perspiration appeared in the very centre of Neville’s forehead and clung to it in an appropriately religious fashion like some crystal caste mark. “I… I… I…” he continued.

Old Pete entered the Swan, Chips as ever upon his heels. Being naturally alert, he spied out the barman’s unnatural behaviour almost at once. “Evening to you, Omally,” he said, nudging the Irishman’s arm. “Haven’t missed anything, have I?”

“Sorry?” Omally, although a man rarely rattled, had been severely shaken by the barman’s frightful disclosure.

“The mime,” said Old Pete. “I’m very good at these. Spied out Norman’s Quasimodo some days back and won an ounce of tobacco. This one looks quite easy, what’s the prize?”

Omally scratched his whiskers. “What are you talking about?”

The old loon put his head upon one side and stroked his chin. “Is it a film or a television programme?” he asked. “Do I get any clues?”

“It’s a book,” said Pooley, taking the opportunity to retrieve his pint before retreating to a safe distance.

“I… I… I…” went Neville.

“Must be the Bible then,” said Old Pete. “Not that I’ve ever read it. Should say by the look of the stick and everything that it’s either Moses parting the Red Sea or Samson slaying all those Philippinos with the jawbone of an ass.”

Young Chips, who was of a more metaphysical bent, suspected that it was more likely Lobsang Rampa’s The Third Eye, with the caste mark and the glassy stare and what was quite obviously some kind of mantra based upon the concept of self-realization; the I.

Neville slowly replaced his knobkerry, and turned to the cash register where he drew out Pooley’s change, including amongst it thirty shillings’-worth of florins. Preventing patrons from playing Captain Laser machines did not seem to be of much importance any more. “Enjoy your game,” he said, handing the still flinching Jim the money.

Old Pete shook his head. “Can’t abide a poor sport,” he said. “Guessed it in one, did I? Told you I was good. What about the prize then?” Neville, however, had wandered away to the end of the bar where he now stood polishing an imaginary glass with an invisible bar cloth. “What about a drink then?” The ancient turned imploringly towards Pooley and Omally, but the two had taken themselves off to a side table where they now sat muttering over an outspread map. “I won it fair and square,” said Old Pete to his dog. Chips shrugged, he had a bad feeling about all this and wished as usual to remain non-committal.

Jim Pooley ran his finger up and down the cartographical representation of Brentford and made a wash-handbasin out of his bottom lip. “This really is all getting rather dire,” he said. “Spacemen on the allotment, starships on the attack, and the Flying Swan without a darts captain. Are we dreaming all this or can it really be true?”

Omally fingered his beard and examined the tide marks about his cuff. “It’s true enough,” said he, “and I think we might do no better than to apply ourselves to the problem in the hope that a solution might be forthcoming.”

“We’ll have to do something about Neville.” Pooley peered over his shoulder towards the dejected figure. “I can’t stand seeing him like that.”

“All in good time,” said Omally, giving his nose a tap. “I am sure I shall be able to effect some compromise which will satisfy both parties and get us one or two freemans into the bargain. For now though the map must be the thing.”

Jim had his doubts but applied himself once more. “What are we looking for?” he asked very shortly.

Omally took out his Asprey’s fountain pen, which by virtue of its quality had withstood its ordeal by water with remarkable aplomb, or la plume, as the French would have it. “If a pattern exists here I shall have it,” he said boldly. “When it comes to solving a conundrum, the Omallys take over from where the fellow with the calabash and the deerstalker left off. Kindly turn the map in my direction.”

“Whilst you are solving the Enigmatic Case of the Cerean Cipher,” said Pooley sarcastically, “I shall be off to the bar for another brace of Large. I am at least getting pleasure from my newly acquired wealth.”

The ordnance survey map had received more than a little attention on his return. “Looks very nice,” he said. “I didn’t know that there was a streak of William Morris in you, John. Taken to designing wallpaper, is it?”
