Mobile Phone Mystery solved

After reading a lot of detection fiction over the last year or so, I like a little bit of mystery in my life.  Just this week a few have cropped up. 
The first was when it seemed like Harry's car was eating my mobile phone piece by piece.  The back of it falls off regularly and I snap it back on - maybe 20 times a day.  On Monday it fell off in Harry's car that I was driving while he was in Algeria.  No one could find it.  I actually shook out all the footrests and removed all the bits of stuff that have accumulated over the last year or so.  looked down the sides of the seats.  Theo even shone a torch.  No luck.  So the phone is not looking good with all its bits exposed like that.  Every time I got in the car i would look again.  Then on Tuesday, the battery disappeared.  It was then a real mystery.  I thought that a child (Toby?) was tricking me, but he assured me (over pain of no more runescape) that this was not so.  So double dilemma.  The phone is quite necessary now with the kids all over the place at different times and stuff.  I was wondering which kind of detection strategy would work the best when it came to me that I was going to have to go where no person has been before - under the carpet.  Sure enough, there they were.  Together.  How they got there is very hard to understand, but luckily I reinserted everything and it worked again. 
The next mystery was a missing person.  Toby.  Caught the bus home, rang to say that evil bus driver from hell had refused to stop at his stiop and so he wa about 2 miles away and walking home.  Had cleared instructions with Theo as to direction to take.  As it was raining I thought i would go and pick him up.  Nowhere to be seen.  Was not answering own phone so deduction was either a. kidnapped; b. phone out of charge; c. lost phone.  Most likely were b. and c. 
Came home and had a think and a quiet worry.  Could he have walked the wrong way (possible). Or could he have 'stopped off' somewhere.  Decided on another trip up the road and found him at the end of the street.  It turned out that he had called into the Percy Arms for a drink.  Water with ice.
At least the mysteries are more Stephaie Plum that Lisbeth Salender.
