garden and saw a magpie, possibly the same one as earlier, swaggering confidently across the lawn. âItâs well out of range, Frank.â He grinned. âItâs keeping a respectful distance from you.â
âAnd he knows it,â Jenny growled. âI tell you he knows what heâs doing â the damn thing is taunting me. Itâs taunting me. I promise I am going to buy an air rifle, one that is both powerful and accurate. I would have done it a long time ago but it would have distressed Alison ⦠The time is coming, though. I tell you the time is nigh. Well nigh. She attends elderly personsâ yoga every Monday and Friday afternoon in the village hall, and thatâs when Iâll lay in wait for the blighter and any friends he cares to bring with him. If he has any. But to continue ⦠the lock puzzled me. It puzzled all of us.â
âThe lock?â Hennessey turned and glanced at Jenny.
âYes, the lock on the main door through which the felons gained entry. I suspected the son â¦â
âNoel,â Hennessey reminded him.
âYes, Noel Middleton. Hasnât he mentioned it?â Jenny continued. âThe door had two locks.â
âTwo?â Hennessey echoed.
âYes, a barrel lock and a mortise lock which was the lock which really secured the door. It appeared to us that the intruders smashed a pane of glass next to the door which enabled them to reach a hand in and turn back the barrel lock and thus open the door,â Jenny explained. âQuite a simple entry.â
âSo the mortise lock wasnât locked?â Hennessey interrupted. âThat is strange.â
âIt seemed not to be,â Jenny confirmed, âbut apparently that is, or was, very strange â totally out of character. I recall talking to the son, Noel, when he had travelled from his university following the murders. He was at Durham, I seem to remember and, incidentally, was very rapidly cleared of all suspicion of involvement in the murders either directly or vicariously.â
âYes, yes,â Hennessey grunted, âwe do not think he is in any way implicated.â
âGood ⦠I am pleased we were right about that ⦠but Noel did inform us that he thought it highly unusual for the mortise to be unlocked,â Jenny explained. âYou see, it appeared to have been the case that Mr Middleton was very security conscious and he insisted that the mortise be locked at all times ⦠and I mean at all times. Each member of the household carried a key to the mortise lock and another key to the lock was kept captive inside the house on a length of lightweight chain â the sort of chain youâd use to attach a bath plug to the bath.â
âYes.â Hennessey nodded. âI understand.â
âBut that key, which was there as a permanent fixture so that no one could be trapped in the house in the event of fire, could not be reached from outside the door by smashing any of the glass panes,â Jenny explained. âIt was kept on a hook hidden from view and well out of reach of anybody outside.â
âInteresting,â Hennessey commented. âI see where you are going.â
âSo when the son, Noel, was told that the mortise appeared to have been unlocked that night and entry had been gained only by turning the barrel lock, the son used words or expressions like âastoundingâ, âunheard ofâ and ânext to impossibleâ for the mortise to be left unlocked.â
âSo there is a story there,â Hennessey observed.
âThere may be, but we must not jump to conclusions â¦â Jenny helped himself to another muffin. âYou see, equally it may be nothing more than a terrible coincidence that the one night the mortise was left unlocked because of an oversight on the part of one member of the household was the very night that the home was invaded. Though, frankly, I
