Things that go bump in the night

Last night we were fast asleep when Steven shook me and asked "Did you hear that?" "What?" Actually I was really asleep so it was probably more like "Whaa...zzz." "Those two thuds".
I hadn't heard anything and I wasn't about to wake up properly, thrown on clothes, go downstairs, find the source of the thuds, deal with potential burglars or any other catastrophe. So I let the man deal with it and went back to sleep.
A little while later (I have no idea how long, I was asleep), I was shaken awake again by the returning hero. "I found it" "Hmmm?" "The problem" "Hmmm" "Don't you want to know what it was?"
I knew I wasn't going to get back to sleep until he had told the whole story. And here, for your edification, is the tale of things that go bump in the night.
I made chicken and dumplings yesterday (new recipe that replaces the butter or suet with sour cream) but the dishwasher was full so we stacked the dirty plates on the countertop. The thuds were the two plates hitting the kitchen floor. Luckily the plates were 1970s Royal Doulton Marbella stoneware and the floor is vinyl, so they are intact. If we'd had ceramic tiles they would have shattered, and we've lost quite a few china plates on the vinyl over the years.
How had the plates ended up on the floor? Steven says they had been licked clean so I can only surmise that one or more of these felines was the culprit. They were found huddled under the kitchen table doing their best to look innocent.
The question is: How can we identify the guilty party(ies)?


This one is good at catching water. Would his paw skills be equal to the task?


This one had a definite guilty air about her.


And this one looks as if he's already in gaol. That's where all three are headed if they don't cut out the nocturnal shenanigans.


One thing we can be sure about is that this cat is innocent. That's because he thinks he's a dog and he was with his doggy buddies far from the scene of the crime.
The other thing is that once Steven had reported his tale of valiant endeavours to me he fell straight back to sleep while I tossed and turned for a couple of hours. Quelle surprise!
