Actor Benedict Cumberbatch has made peace with his mystery cyber-stalker after she baked him a cake to apologise for spying on him.

The Sherlock star was left rattled earlier this year (13) when he discovered his daily movements were being posted on microblogging website Twitter.com.

Cumberbatch was so unnerved, he considered calling cops, but the issue resolved itself when the 'stalker' was revealed to be a female neighbour who baked him a sweet treat to say sorry for scaring him.

The actor was flattered by the tasty gift but had to decline it as he needs to stay slim to play British super-sleuth Sherlock Holmes on Tv, telling British magazine Event, "I'm trying to look after my Sherlock jawline, otherwise I'd have loved the cake."
