I would inform the client/husband and if it continues then I will head to the police station to report her hand them the clients phone number everything including the stuff she posted through your letter box. Then it will be upto the police to contact the client and take it from there as you do not have her phone number or any other contact details so they will have to go through the husband.

I do not agree with what some other lady said - wait till you are harmed. - No way. Best get it nipped in the bud before it escalates. How do we not know if his wife is a syco bitch and will do something horrific. You do not want it to reach to that scale.
Also this shows you are not scared and you are not doing any illegal activitiy. He sought your services which you provided.

You are not in the wrong and have the right to seek police help.

I second this entirely. Act now before it escalates. She will feel like she has control/power over you which she does not! The police will back you but it does take time for them to process everything so best to call them, make a report, then go in and speak to someone and hand over the evidence. Sooner the better.

Hope you get it sorted x

I certainly would not bother with the police or anyone or forum until a crime has actually been committed.
Finger prints? think you have been watching too may episodes of CSI - ignore and move on

Probably having a relative who was tortured and dismembered in their home by three neighbours has taught me a bit more about personal safety and home security... than some fictional TV entertainment.

I actually think this is the best idea of all. Besides, how did "she" found your address? 

My guess is that like most ladies on here we text address and the idiot did not delete his texts etc. So the address is either in text if she did text him or She did not text him full address and the Client remembers where she lives and spilled all to his wife.

My gut is saying this is actually the client.  Designed to make you panic and interfere with your work and your cash. 

Either way, continue to work as normally as you can.  Keep anything that comes through.  If you know the client, I would ban him instantly, me personally I would send him a text to say he's banned due to the letter that was posted and if there is any further he will be reported to the police and they can deal with this issue legally.

I agree with Nora B on this.

I've had a client tell me his wife had been to my address (it was my working place) and spoken to all my neighbours and was reporting me to HMRC. 

When I asked him how she had my address he was a little non-plussed and came up with a story about how she worked it out from his car parking ticket.  Really?  His wife saw a car parking ticket from a town centre car park and instantly jumped to the conclusion he had seen an escort and not only that she also worked out which apartment out of all of those in the town centre he had seen said escort in? 

He then came up with the story that he told her my address!  In all reasonableness if a guy gets caught out who in their right mind would give his wife that sort of ammunition, he would deny it to the hilt or make up an address or even claim he had forgotten where.

When asked which neighbours she had spoken to he described some foreign students that had lived in the block months previously who he may have seen when arriving for bookings but they had moved out a long time before the incident.

When I asked him about HMRC he told me she had reported me as I didn't pay my taxes.  As I do submit tax returns which include my escorting income that is hardly an issue to me.

When this didn't work he then came up with the story that he had given his wife an oral STI, clearly the implication was that I had given that to him.  I was up to date with my tests and instantly went and got rechecked and low and behold my tests were negative!

The client was clearly trying to spook me with his fantastical stories that clearly made his drab little life more tolerable.

So it's highly possible it is your client and not his wife that posted the pictures through your letterbox.  Some people just like to cause drama.

I'd say to carry on as usual and do not contact the client. I always find the best action with anything designed to provoke alarm or anxiety is to ignore completely and pretend it hasn't affected you - this comes from ongoing abuse from a sociopathic ex who does stuff like this, and more, to cause me anxiety. I have learned that no response causes them to stop for a bit. I have also learned that by the police giving them a visit to give them a friend hint to stop what they are doing also symbolises that their actions have caused you alarm, and they therefore continue, despite the threat from the police.

I have had emails claiming to be a wife who found out and hired a PI to follow me, disclosing my full name and address. This, of course, was my ex trying to fear me into stopping work and therefore becoming under financial stress. Under the malicious communications act, this is a crime, but police really can't do much without hard evidence. Even with evidence, such as malicious and threatening emails from someone, enough to press charges, the accused can easily get off by saying that it wasnt them who sent the email even though it came from their email address. Again, this is based on experience.

So unless you have video footage of the person posting these threatening photos, along with a clear image of what they are actually posting on the footage, there really isn't much evidence to prove it was them and charges to be pressed. All that will happen is that you get stressed out for a few weeks with police visiting you for statements, then waiting on phone calls from the police to confirm the outcome, all the while you dont work because you are so stressed. Trust me, just ignore and keep doing what you are doing. If there are more incidents, keep a record and if you have solid evidence, then go to the police.

These assholes want a reaction, don't give them one.

Well sending threatening and abusive mail through someones door could be considered a crime primarily under Malicious Communications and Harassment.A police website I looked at say's this about it:The Malicious Communications Act 1988 is a British Act of Parliament that makes it illegal in England and Wales to "send or deliver letters or other articles for the purpose of causing distress or anxiety".
Regardless of whether there are fingerprints on it or not it is worth keeping hold of in case anything should escalate.It is quite likely the police will have a word with this person and that would be enough for them to back off.

The op just said it was a note through the door and quite clearly was not threatening or abusive. Could just be a resentful punter or neighbour.

I got a really nasty letter a few months ago from a neighbour stating that my refuse bin was put in the "wrong place" which I ignored! This kind of communication is usually from people in our society that really do need to get a life.

If you went to the Police with this note from someone you may or may not know, they would just laugh.
If you feel threatened or abused and have evidence, then sure, go to your local cop shop and they will deal with it accordingly.

Ignore and move on!

No.The OP stated in one of her earlier posts (page 1 of the topic)that the letter said things in it such as calling her a whore.If that isn't abuse I am not sure what is.That would fall under the Malicious Communications act.So is a crime.
Up to her whether she wants to get the police involved but to imply a crime hasn't been committed yet and the police would laugh at her at the moment isn't technically correct.
