at 9.35, she made a telephone call to her son. The son was out, but his answering machine picked up the call. This is it.’ He nodded for Gilmore to start the tape.
A bleep. Then, Hello, son. It’s mother. You needn’t worry anymore about… Just a moment, there’s someone at the door… Vague sounds as the tape continued, then another bleep. Gilmore jammed down the Stop control.
The room was dead quiet.
‘She put down the phone,’ continued Frost, ‘and went to the front door. She squints through the spy-hole, likes what she sees, so this nervous woman undoes the chain, draws the bolts and welcomes in the bastard who’s going to rip out her intestines.’ He took the cigarette from his mouth and spat out a shred of tobacco. ‘You’re all a lot smarter than I am, so let’s have some brilliant suggestions. Come on — you’re a nervous woman of seventy-six. Who would you let into your flat at night — apart from a toy-boy with his own teeth and a big dick?’
Burton raised his hand. ‘Something we’ve never considered, sir. She’d never let in a man — but what if the Ripper was a woman?’
Frost chewed on his lip as he thought this over. ‘It’s possible, son. It would explain a lot, but my gut reaction is against it. We’ll keep it in mind, though.’
WPC Jill Knight raised a hand. ‘If she’d phoned for a doctor, she’d let him in.’
A buzz of excitement.
‘You’re right,’ said Frost. ‘She’d let a doctor in.’
‘Or a priest,’ added Gilmore. Purley was still his number one suspect.
‘Or a priest,’ agreed Frost. ‘OK, son You can check on the curate. We want to know where he was last night. And you, Jill. Find out who her doctor was. See if she asked him to call last night and even if she didn’t, find out where he was at 9.35. Anything else?’
He waited. Nothing. He took out a fresh cigarette then threw the pack to Burton to offer around. ‘I’ll tell you some thing that worries me.’ He struck a match on the table leg. ‘This time he took no money. He didn’t ransack the bed room. Over a hundred quid in her purse in full view on the sideboard and it wasn’t touched. Now Sergeant Gilmore suggests something disturbed the Ripper and he had to hoof it off before he could nick anything.’ He blew out the match and let it drop to the floor. ‘But stupid sod that I am, I can’t buy that. This bloke is icy cold. Nothing panics him. I reckon money’s never been his motive.’
‘So what is his motive?’ asked Gilmore.
‘Killing,’ said Frost. ‘I reckon he gets his kicks out of cold, bloody killing.’
The room went quiet. Chillingly quiet. This had the ring of unpalatable truth.
‘Right.’ Frost slipped down from the desk. ‘Let’s play the tape again.’
It was played again, and again and again. Frost, smoking, chewing his knuckles, hunched in front of the loudspeaker. Just a moment, there’s someone at the door… Vague sounds. A bleep. Gilmore’s voice… Mr Watson, this is Denton Police
‘Again,’ snapped Frost. There was something there. Some thing his subconscious had caught but which kept slipping away. ‘This is no damn good,’ he moaned. ‘I want it louder.’
‘It won’t go any louder,’ said Gilmore.
‘We could use the hi-fl equipment in the rest room,’ suggested Burton.
They crowded into the rest room. Gilmore slotted in the cassette and turned the amplifier up almost to its maximum. He pressed Play and the hiss of raw tape crackled from the twin speakers.
The bleep screamed out like an alarm signal. Tape hiss. Hello, son. It’s mother, shouted the old lady, the sound almost hurting their ears.
‘Leave it,’ ordered Frost as Gilmore’s hand moved to turn down the volume. You needn’t worry any more about… Through the mush, a buzzing vibrating sound. Then an other.
‘The door bell,’ muttered Frost. At ordinary volume level it was inaudible.
Just a moment, there’s someone at the door… A rustling, then an echoing bang as if someone had hit a microphone. She had put the phone down. Fading footsteps as she padded up the hall to the front door, eager to let in her murderer. Now the tape background roar was paramount. Frost pressed his ear to the speaker. ‘Nothing. I imagine she’s giving him the eyeball through the peep-hole. Ah…’ He moved back. Just about audible, the sound of bolts being drawn and the chink of the chain being removed. The lock clicked. The door opened. The woman said something, but it was so faint and the background so loud, they couldn’t distinguish a word. Then a screaming bleep as the automatic cut-off operated.
‘Let me have a go,’ said Burton, elbowing Gilmore away and adjusting various controls on the hi-fl’s graphic equalizer which could cut and boost individual frequencies. ‘Now try it.’
By now, they almost knew every squeak, rustle and click off by heart. When the woman spoke after opening the door it was clearer, but tantalizingly not clear enough for them to make out a single word. ‘Again,’ ordered Frost. But Mrs Watson might have been talking in a foreign language for all the sense it made. God, thought Frost. She could be naming her killer — ‘Come in, Mr Ripper of 19 High Street, Denton’ — yet they couldn’t understand what she was saying.
‘Try the earphones,’ said Burton.
The earphones were better, but still not good enough.
‘Let me have a go,’ said Jill Knight, adjusting the earphones over her tightly curled hair. She listened and frowned. ‘Again,’ she said. The frown was deeper, but this time her lips were moving as if she was repeating what she heard. She took off the earphones. ‘She’s saying, “Oh, it’s you. I didn’t expect you so soon.” ’
They played it again through the speaker. The WPC was right. Oh, it’s you. I didn’t expect you so soon. Frost’s head bowed. He had been hoping for so much and this was nothing.
‘She knew him,’ said Burton.
‘And he came sooner than expected,’ muttered Frost. ‘I think that’s called premature ejaculation.’ The resulting laughter lifted his depression. ‘Let’s hear it again.’ He waved aside the moans that they knew it off by heart. ‘Indulge an old man’s whim. We might have missed something.’
Again they listened, but only half-heartedly. The tape had told them everything it could. There was nothing they had missed. Oh, it’s you. I didn’t expect you so soon. The thud of the door closing behind him, then the hiss and clanking as raw tape scraped past the replay heads when the automatic cut-out operated. A bleep.
Frost was sitting bolt upright in his chair, an unlit cigarette drooping in his mouth. ‘Again — just the end bit — and the volume as high as you bloody well like.’ Gilmore spun the volume control to its maximum. At first they didn’t spot it. ‘You must be stone bleeding deaf,’ roared Frost. ‘Again… and listen this time… There!’ And this time they heard it. A fraction of a second before the message switched off. The closing of the front door. The hiss, roar and crackle as the tape bumped past the heads then… a boxy, metallic chink.
Burton scratched his head. ‘Could be anything, Inspector. He could have bumped against the table as he came in.’
‘Even if he did,’ said Frost, ‘there was nothing on the hall table that would chink. That is definitely a metallic sound.’
‘There could have been something on the table — some thing valuable — but he took it away with him,’ suggested Gilmore, who was feeling left out of things.
‘I thought I heard something chinking as he came through the door,’ said the WPC.
‘Did you?’ exclaimed Frost excitedly and he was up on his feet, jamming his finger on the Rewind button and playing the tape through again. ‘Yes… there!’ And through the mush, as the man stepped through the door, a faint metallic chinking sound… then another.
They didn’t hear the door open. ‘What’s going on in here?’
‘Piss off!’ said Frost. ‘Oh, sorry, Super… didn’t know it was you.’ He played the tape through yet again for Mullett who tried to look as if he knew what Frost was driving at, but obviously didn’t.
‘That noise, sir. At first we thought he’d bumped into the hall table and jolted something on it, but we now reckon that whatever it was, he brought it in with him and dumped it on the hall table.’
Mullett considered this. ‘It might help if we knew what it was. But we don’t.’
‘I think I do,’ said Frost. He looked around the room to make sure he had everyone’s attention. “What about a new security chain?’
Mullett frowned. ‘A security chain?’
‘Old Mother Watson had arranged to have a stronger one fitted,’ Frost told him. ‘And that’s who she let in
