A study in hummus

John Watson was standing for thirty minutes and looked at thrilled Sherlock Holmes, which jumps over old mafioso's corpses. Being on cloud nine, the detective shows off to the police. He shows them new clues. Deadmen's got shot in the head, but it didn't caused death. He noticed that the rose in the buttenhole, the left shoe sole and trousers' legs are covered in silverish blue fur. Corpse's shirt wasn't precisely ironed and it was a little to big for that man. Financial problems? Elegant clothing borrowed from trusted family member?- Sherlock deduced. The best thing was that there was a "message" near the corpse. Black lotus flower made from origami. Sentiment? Reminder? Attempt to direct the accusations to somebody else?
- ah, John, gangstas' disputes never were so exciting!- they were going back in the cab to the flat. Men behaves like a child.
- Sherlock, calm down, you're going to destroy that vehicle.
When the car stopped, the detective pelted to the doors with the 221b number. John, as always, has to pay. He took the charge, and when he turned around, he was literally dragged to the house.
- John, meet Ahmed, he's new mrs. Hudson's boyfriend- in the corridor there was thirty- something year old men in pink apron. There was a wide smile on his dusky face. In his hands he holds baking tray with incerdibly exoting smelling dish.
- Maybe a falafel?- he asked with strong accent. John wanted to refuse politeky, but Sherlock took a ball made of cheackpeas and put in his mouth.
- Delicious!- Ahmed looks like he didn't understand.
- Oh! Boys you're back- mrs. Hudson appeared from the kitchen. Older woman stanted next to his partner.- i can see that you've met Ahmed, he arrived in England teo months ago. I've met him yesterday on cook lessons. He doesn't understand much, but his kebab is delicious- woman hugged him.
- That's great mrs. Hudson! I'm happy of your lucky, but i've got a case to solve, i need to go- in few jumps he was at the top of the stairs.
John ran after detective.
- The case is solved! If the gardener has got a blue cat, thr murderer is the uncle's housemaid!
-  How do you know that!?
- Fur, that cetainly belonged to a cat, was on trousers' legs, but not on sleeves. He wasn't emotionally related to it, which it didn't belong to him, however the fur was on fresh rose. That's mafioso, not a gardening lover. The cat must belonged to the victim's gardener. Here I've had a moment of doubt, but inspector Lestrade just called me. The shirt and the suit belonged to victim's rich uncle. There were not precisely ironed, the uncle has got a housemaid. If she only had the opportunity, she would quit the job. She fell in love with the deadman without reciprocity. When she found out that he has someone, she decided to kill him. But is that really important my dear John? Let's make vegan hummus!
- Hummus!?
- That's elementary my dear Watson. If mrs. Hudson and Ahmed can be together, we can be to! We can't have kids, but we cah have as much hummus as we want!
- Sherlock, was that a declaration of love!?
The Detective was to busy by measuring the suitable quantity of tahini to say something more, but the answer could be only one.
