'No. All the main doors are security locked and he would have to operate the release switch.'
'Damn,' said Frost. The wife rowing with another man around midnight was a complication he would have preferred to be without.
'And I've spoken to the owner of Denton Shopfitters,' continued Liz. 'He phoned the store just before midnight to check on their progress and spoke to the husband.'
'You're very thorough,' said Frost ruefully.
'Mr. Cassidy is suggesting that the man the neighbours heard could have been Sidney Snell.'
Frost treated this with scorn. 'You don't have a row with a man who breaks into your house… you scream and shout at the bastard. Did the neighbours think she sounded frightened?'
'No. They said it was a heated row.'
'Well then.. He stood up. 'Sidney Snell is not a killer. Don't waste your time going down that road.' He glanced up at the clock, then flicked his scarf over his shoulder and stood up. 'Frogman time … if anyone wants me I'll be paddling in the canal.' At the door he paused, trying to remember what it was he intended asking Liz to do. Oh yes. He wanted her to check with the Council to find out who used to live in the derelict houses where Lemmy's body was found. But the poor cow looked ready to drop and she had a three-body postmortem to attend. He'd get someone else to do it.
PC John Collier pulled at the oars and winced as his blistered hands throbbed. He wished he hadn't volunteered for this. He'd thought it would be pleasant, scudding the boat across the water, watching the frogmen plunge in with a kick of their flippers. But it was hard, back-breaking work. There was a strong wind blowing the boat in the opposite direction to which he wanted it to go.
'Steady as she goes, Number One.' PC Ken Ridley, systematically prodding the murky bottom of the canal with a long pole, was doing his captain of the battleship act which got progressively less funny with constant repetition. Ahead of them a line of bubbles marked the progress of one of the police frogmen.
Frost sat on the bank, moodily surveying the proceedings and sucking at a cigarette while tossing small stones into the water. It was cold and windy and he had the strong feeling this would be a waste of time. The canal at this point was crossed by the road bridge which made it the ideal point from which to hump junk out of a car boot and chuck it into the black soup of the stagnant water. Much of this had been retrieved by the frogmen and the towpath was cluttered with foul-smelling heaps. There were sodden mattresses, a couple of bundles of carpeting that looked almost new, but which would never lose the ripe canal smell, a black plastic bag which turned out to be full of offal from a butcher's shop and the bloated carcass of a long-dead goat. Particularly revolting was a soggy cardboard box crammed full with maggoty chickens' heads and feet. 'All we want now is a few spuds and we've got ourselves our dinner,' he commented bitterly, pulling a face as the wind changed and drove the smell of putrefaction straight at him. Many years ago, when he was a small child, he had sat on this same towpath, probably not far from this same spot, and had fished for tiddlers. But there was nothing living in the water now. Denton Union Canal, long since abandoned by the once thriving barge trade, was now a choked, evil-smelling backwater.
A frogman's head broke the surface. He had been tying a rope to something enveloped in mud at the bottom and was signalling for Collier and Ridley to haul it up. A bulging, black plastic dustbin sack was dragged into the boat. Frost's heart sank. It was the right size and shape for a young boy's body.
The boat bumped against the side of the towpath and the two policemen lifted out the sack which streamed water from holes, apparently punched in it to make it sink. They laid the sodden mass alongside Frost who regarded it gloomily, dreading to think what was inside. He stood up, chucked his cigarette into the canal, then gave the sack a tentative prod with his foot. Something soft and yielding, like flesh… He crouched down and sliced through the string tying the neck of the sack with his penknife. He peered inside. A sodden mass of water-blackened human hair. He looked up at Ridley and nodded grimly. 'It's the boy.' He pulled the neck of the sack open wider, then the cold sweat of relief flooded through him. He looked up again at Ridley. 'I'm a prize twat!' he said. It wasn't human hair. He reached inside the sack and pulled out a heavy sodden fur coat. He had no idea what a mink coat looked like, but this, even dripping with filthy canal water, looked expensive. As did the silver fox cape which was under it. At the bottom of the sack was a grey plastic bag which was tied tightly with clumsily knotted string and held something heavy. His penknife sawed through the string, leaving the knot intact so Forensic could submit it to their scrupulous examination and come up with sod all. Inside was a brick, put there to ensure the sack sunk, and also a jumble of jewellery. The haul from Robert Stanfield's house.
Frost stared at it. Why had it been stolen, then dumped? It suggested an insurance fiddle, although the furs and jewellery looked genuine enough. He put everything back inside the plastic sack. 'Trot it down to the station. We'll get Old Mother Stanfield in to identify it.'
Ridley's pole had prodded something that belched up large, rancid-looking bubbles which burst to exude a stomach-churning smell. He signalled to the frogmen, but before they could respond, Frost's radio squawked. Control calling him urgently. 'Can you get back here at once, inspector. We've received a ransom demand for the missing boy.'
'What's the betting it's a bleeding hoax?' muttered Frost, clicking the radio off.
He took one last look at Collier and Ridley, who were hauling up something slimy and phosphorescent that broke in half as they tried to get it into the boat, then made for his car.
There was quite a crowd waiting for him in the incident room including Cassidy, Hanlon, Burton and Harding from Forensic, all looking grim. 'So where's this ransom demand?' asked Frost.
Cassidy pointed to a padded envelope lying on the desk. 'It came in this morning's post.' The typed label was addressed to The Missing Boy Officer, Denton Police Station.' The postmark, date-stamped the previous evening, was that of the main Denton post office. 'This was inside.' He handed Frost a sheet of white A4 paper which had been slipped inside a transparent cover for protection.
The message was printed out on a dot matrix printer in draft mode. Frost read it aloud.
'To the officer in charge:
'I have the missing boy the enclosed should enable you to convince Sir Richard Cordwell, Managing Director of the Savalot supermarket chain, that this is genuine.'
Frost paused. 'What was enclosed?'
Cassidy shook out a matchbox from the padded envelope and, holding it carefully by the corners, passed it to Frost without a word. Frost pushed open the tray, and stared in horrified disbelief. 'No!' On a bed of blood-flecked cotton wool lay a severed human finger. He looked away, then back again in the hope it wouldn't still be there. A tiny finger, the flesh waxen, grime under the nail, dried blood caking the severed end. It almost looked too small to be real, but Forensic confirmed it was from a child of seven or eight years old.
Frost stared at nothing, lost for words. Then, very carefully, he closed the tray and handed the matchbox back to Cassidy.
He poked a cigarette in his mouth to compose himself before he resumed reading the letter.
'I am sorry about the first boy. That was an accident, but if Bobby Kirby is to die, that will not be an accident. It will be because you have failed to carry out my instructions.
'1. For the safe return of the boy, I require to be paid the sum of 250,000. This money is to be paid to me by Sir Richard Cordwell, Managing Director of the Savalot supermarket chain. This money will be a flea-bite to him.
'2. I have also written to Sir Richard Cordwell explaining how the money is to be paid. If he refuses to pay, the boy will die and his company's name will be mud.
'3. Your job is to convince Sir Richard he must pay and then to stay out of it. You will take no further part in the proceedings if the boy is not to be harmed further. Any sign of the police when the money is handed over to me even if a police car should accidentally pass by then the boy will die. I will be monitoring all police radio calls to ensure you keep out of it.
'4. Any attempt at stalling for time and the boy will lose another finger.
'5. The boy is well, but in some pain. He is hidden where you will never find him. Do what I request and I will tell you where he is. Ignore my requests and you will never see him again.
'6. I am sending a copy of this letter and a cassette tape to the Denton Echo so the public are aware that it is up to Savalot whether the boy lives or dies.'
'Give credit where credit's due,' muttered Frost, 'but he's a cold, calculating, business-like bastard.' He read it through again, silently this time, then tossed it on the desk. 'He forgot to sign it.'
'There were no prints on it,' said Harding from Forensic.
